Found: genes that sway the course of the coronavirus – Science Magazine

Thursday, October 15th, 2020

A study of some of the sickest COVID-19 patients, such as those placed on ventilators, has identified gene variants that put people at greater risk of severe disease.

By Jocelyn KaiserOct. 13, 2020 , 1:25 PM

Sciences COVID-19 reporting is supported by the Pulitzer Center and the Heising-Simons Foundation.

Its one of the pandemics puzzles: Most people infected by SARS-CoV-2 never feel sick, whereas others develop serious symptoms or even end up in an intensive care unit clinging to life. Age and preexisting conditions, such as obesity, account for much of the disparity. But geneticists have raced to see whether a persons DNA also explains why some get hit hard by the coronavirus, and they have uncovered tantalizing leads.

Now, a U.K. group studying more than 2200 COVID-19 patients has pinned down common gene variants that are linked to the most severe cases of the disease, and that point to existing drugs that could be repurposed to help. Its really exciting. Each one provides a potential target for treatment, says genetic epidemiologist Priya Duggal of Johns Hopkins University.

In a standard approach to finding genes that influence a condition, geneticists scan the DNA of large numbers of people for millions of marker sequences, looking for associations between specific markers and cases of the disease. In June, one such genomewide association study in The New England Journal of Medicine (NEJM) found two hits linked to respiratory failure in 1600 Italian and Spanish COVID-19 patients: a marker within the ABO gene, which determines a persons blood type, and a stretch of chromosome 3 that holds a half-dozen genes. Those two links have also emerged in other groups data, including some from the DNA testing company 23andMe.

The new study confirmed the chromosome 3 regions involvement. And because 74% of its patients were so sick that they needed invasive ventilation, it had the statistical strength to reveal other markers, elsewhere in the genome, linked to severe COVID-19. One find is a gene called IFNAR2 that codes for a cell receptor for interferon, a powerful molecular messenger that rallies the immune defenses when a virus invades a cell. A variant of IFNAR2 found in one in four Europeans raised the risk of severe COVID-19 by 30%. Baillie says the IFNAR2 hit is entirely complementary to a finding reported in Science last month: very rare mutations that disable IFNAR2 and seven other interferon genes may explain about 4% of severeCOVID-19 cases. Both studies raise hopes for ongoing trials of interferons as a COVID-19 treatment.

A more surprising hit from the U.K. study points to OAS genes, which code for proteins that activate an enzyme that breaks down viral RNA. A change in one of those genes might impair this activation, allowing the virus to flourish. The U.K. data suggest there is a variant as common and influential on COVID-19 as the interferon genetic risk factor.

Other genes identified by Baillies team could ramp up the inflammatory responses to lung damage triggered by SARS-CoV-2, reactions that can be lethal to some patients. One, DPP9, codes for an enzyme known to be involved in lung disease; another, TYK2, encodes a signaling protein involved in inflammation. Drugs that target those two genes proteins are already in useinhibitors of DPP9s enzyme for diabetes and baricitinib, which blocks TYK2s product, for arthritis. Baricitinib is in early clinical testing for COVID-19, and the new data could push it up the priority list, Baillie says.

The chromosome 3 region still stands out as the most powerful genetic actor: A single copy of the disease-associated variant more than doubles an infected persons odds of developing severe COVID-19. Evolutionary biologists reported last month in Nature that this suspicious region actually came from Neanderthals, through interbreeding with our species tens of thousands of years ago. It is now found in about 16% of Europeans and 50% of South Asians.

But the specific chromosome 3 gene or genes at play remain elusive. By analyzing gene activity data from normal lung tissue of people with and without the variant, the U.K. team homed in on CCR2, a gene that encodes a receptor for cytokine proteins that play a role in inflammation. But other data discussed at last weeks meeting point to SLC6Z20, which codes for a protein that interacts with the main cell receptor used by SARS-CoV-2 to enter cells. I dont think anyone at this point has a clear understanding of what are the underlying genes for the chromosome 3 link, says Andrea Ganna of the University of Helsinki, who co-leads the COVID-19 Host Genetics Initiative.

The U.K. genetics study did not confirm that the ABO variants affect the odds of severe disease. Some studies looking directly at blood type, not genetic markers, have reported that type O blood protects against COVID-19, whereas A blood makes a person more vulnerable. It may be that blood type influences whether a person gets infected, but not how sick they get, says Stanford University geneticist Manuel Rivas. In any case, O blood offers at best modest protection. There are a lot of people with O blood that have died of the disease. It doesnt really help you, says geneticist Andre Franke of the Christian-Albrecht University of Kiel, a coleader of the NEJM study.

Researchers expect to pin down more COVID-19 risk genesalready, after folding in the U.K. data plumbed by Baillies team, the COVID-19 Host Genetics Initiative has found another hit, a gene called FOXP4 implicated in lung cancer. And in a new medRxiv preprint posted last week, the company reports that a gene previously connected to the effects of the flu may also boost COVID-19 susceptibility only in men, who are more likely to die of the disease than women.

Geneticists have had little luck so far identifying gene variants that explain why COVID-19 has hit Black people in the United States and United Kingdom particularly hard. The chromosome 3 variant is absent in most people of African ancestry. Researchers suspect that socioeconomic factors and preexisting conditions may better explain the increased risks. But several projects, including Baillies, are recruiting more people of non-European backgrounds to bolster their power to find COVID-19 gene links. And in an abstract for an online talk later this month at the American Society of Human Genetics annual meeting, the company Regeneron reports it has found a genome region that may raise the risk of severe disease mainly in people of African ancestry.

Even as more genetic risk factors are identified, their overall effect on infected people will be modest compared with other COVID-19 factors, Duggal says. But studies like the U.K. teams could help reveal the underlying biology of the disease and inspire better treatments. I dont think genetics will lead us out of this. I think genetics may give us new opportunities, Duggal says.

Genetics of Height and Risk of Atrial Fibrillation: A Mendelian Randomization Study – DocWire News

Thursday, October 15th, 2020


Observational studies have identified height as a strong risk factor for atrial fibrillation, but this finding may be limited by residual confounding. We aimed to examine genetic variation in height within the Mendelian randomization (MR) framework to determine whether height has a causal effect on risk of atrial fibrillation.

In summary-level analyses, MR was performed using summary statistics from genome-wide association studies of height (GIANT/UK Biobank; 693,529 individuals) and atrial fibrillation (AFGen; 65,446 cases and 522,744 controls), finding that each 1-SD increase in genetically predicted height increased the odds of atrial fibrillation (odds ratio [OR] 1.34; 95% CI 1.29 to 1.40; p = 5 10-42). This result remained consistent in sensitivity analyses with MR methods that make different assumptions about the presence of pleiotropy, and when accounting for the effects of traditional cardiovascular risk factors on atrial fibrillation. Individual-level phenome-wide association studies of height and a height genetic risk score were performed among 6,567 European-ancestry participants of the Penn Medicine Biobank (median age at enrollment 63 years, interquartile range 55-72; 38% female; recruitment 2008-2015), confirming prior observational associations between height and atrial fibrillation. Individual-level MR confirmed that each 1-SD increase in height increased the odds of atrial fibrillation, including adjustment for clinical and echocardiographic confounders (OR 1.89; 95% CI 1.50 to 2.40; p = 0.007). The main limitations of this study include potential bias from pleiotropic effects of genetic variants, and lack of generalizability of individual-level findings to non-European populations.

In this study, we observed evidence that height is likely a positive causal risk factor for atrial fibrillation. Further study is needed to determine whether risk prediction tools including height or anthropometric risk factors can be used to improve screening and primary prevention of atrial fibrillation, and whether biological pathways involved in height may offer new targets for treatment of atrial fibrillation.

A new way of predicting which kids will succeed in school: Look at their genes – NBC News

Thursday, October 15th, 2020

This article about the polygenic score was produced in partnership with The Hechinger Report, a nonprofit, independent news organization focused on inequality and innovation in education. This is part 3 of the series Gifted Educations Race Problem.

Many factors boost a child's chance of success in school like having wealthy parents who can afford tutors. But recent research has raised another possibility one that is discomforting to many the idea that scientists might someday be able to spot the genetic markers associated with academic performance.

To do this, researchers are turning to a relatively new genetic approach called the polygenic score, which assesses a persons likelihood for a specific future based on a combination of genetic variables. Its a research technique that some scientists are using to assess obesity or cancer risk, for instance. Now, researchers are exploring this approach in non-medical contexts, like academic or athletic success.

The scientists studying genetic markers in education are trying to untangle how nature and nurture together explain school performance. In principle, genetic screening might enable teachers to tailor their approach to groups of students. Educators might then more effectively instruct kids together in one classroom, rather than separating students into accelerated and low-level courses, which can deprive Black and brown children and children from low-income families of academic opportunities.

But some researchers fear this gene screening work could be misapplied and used to further racist or eugenic thinking, even though race is a social, not a genetic, classification. Theres an ugly history of proponents of eugenics, who believe in reshaping humanity by breeding superior traits and removing inferior traits, justifying their thinking with genetics. And there are debunked racist theories that have endeavored to falsely connect race and intelligence.

For now, the science is almost entirely based on data collected from people with European ancestry, which limits the conclusions that can be drawn from it, so researchers feel that theyve at least temporarily sidestepped the issue.

But that doesnt mean they arent worried about it and about the other ways this research could exacerbate inequities in education. Screening is expensive, for instance, increasing the odds that privileged students will qualify for extra enrichment or support before their less privileged peers.

Indeed, the idea of predicting students academic performance based on their genes comes with such a raft of ethical questions and unknowns that scientists in the field are urging caution. Polygenic scores are a potentially useful new scientific tool. At the same time, there are clear reasons to be concerned, Stanford University social scientist Ben Domingue said. Were going to have the capacity, with a vial of spit, to be able to predict all these different things.

Scientists and ethicists are also concerned about commercializing this work while the research is still evolving. Already, several companies sell reports to consumers that incorporate polygenic scores for health or various physical characteristics despite the fact that the scores are not perfect forecasters of a persons future.

Researchers in the field want to see more critical discussion of how their work could be applied in educational settings. If we dont pay attention now, systems will be created, constructed around us, responding to our genetic difference, said Sophie von Stumm, a psychologist at the University of York, in the United Kingdom, who studies genetics and education. Its high time to have this discussion. Honestly, were late to the party.

The polygenic score that could help predict academic performance aims to assess genetic markers related to educational attainment. In other words, it combines hundreds of common genetic variants that are linked to the number of years a person stays in school. In 2016, this score could explain about 5 percent of the variation in the level of education completed.

In 2018, researchers studied data from more than a million people across countries and found they could strengthen the polygenic score to explain 11 percent of the variation in educational attainment. That value puts the score on par with factors like a mothers level of education attainment, which explains 15 percent of variation, and household income, which explains about 7 percent.

There are genes that affect educational attainment that is for certain now, said Aysu Okbay, an economist at Vrije Universiteit in the Netherlands who contributed to the 2016 and 2018 studies.

The scores ability to explain variation in years of schooling could improve with more data. Rough estimates indicate about 80 percent of the variation in educational attainment comes from environmental factors the rest is genetic. With enough data, some scientists believe, the polygenic score could get close to explaining 20 percent of the difference in peoples level of education.

If so, the score would be an incredibly powerful single factor for making predictions about an individuals academic future even though the combined environmental variables still eclipse the role of genes. Its really not a puny predictor at this point, Domingue said.

In February, Domingue and his colleagues found that the polygenic score could help identify which groups of high schoolers had been placed into advanced math classes. The score could also point to students most likely to stick with advanced math courses across all four years of high school.

But polygenic scores also come laced with caveats. So many, in fact, that Okbay and her colleagues published a massive list of public FAQs including how the study was designed and whether the research could lead to stigmatization of people with certain genes to help readers interpret their research.

Paige Harden, a clinical psychologist at the University of Texas at Austin and a co-author on the math study likens the polygenic score to a credit score. Neither the polygenic nor the credit score can really forecast what will happen to a particular person. Instead, they provide a rough sense of how people with that score will, on average, fare. The score is better at gauging a groups overall performance than an individuals performance.

Harden and others acknowledge that its still a mystery how the genetic variants behind the score contribute to how far a person gets in school. We dont know what the mechanisms are, Okbay said. We dont know whether its causal or not.

Some research suggests the genes associated with education are related to the nervous system and the brain, raising the possibility that theyre connected to cognitive functions things like strong memory, creativity and perseverance that serve people well in school.

But the relationship could be nuanced. Domingue pointed out that there could be genetic factors that make a person more likely to be a supportive parent, which, in turn, would correlate to better school performance in their children. Because the child and parent share DNA, the polygenic score could capture gene variants in the child that explain educational performance but actually reflect the parents behavior.

There is also an enormous shortcoming in the datasets used for this research: Virtually all are built with DNA from people of European ancestry. Although there are biobanks in the works in Asia and Africa that could address this omission, for the time being, the scores are essentially only applicable to people of European descent. Youre basically developing a tool thats only useful for one segment of the population, Harden said.

Given all of these limitations, most scientists believe it would be unlikely, and inappropriate, for educators to use polygenic scores to determine student placement in specific classes or schools. Will someone be mad enough to track or stream on the basis of genetic predispositions? von Stumm said. Fortunately, I think were far from that.

There could be other ways of using this genetic information. Once genetic variants are better understood and enough data is in hand, for example, it might be possible to identify children with a predisposition to learning disabilities and intervene early. In May, von Stumm and her colleagues published a paper exploring whether a toddlers polygenic score for educational attainment could identify children at risk for language or literacy delays later in life. The conclusion: Were not there yet.

Critics caution that there is too much to establish ethically and scientifically before we confront those scenarios. Someday well understand the genetic contribution to educational success or to life success but it will be our grandchildren who understand it. It wont be us, bioethicist Arthur Caplan at NYU Langone Health said.

And even if we understood this information, its not clear how to best use the scores in schools. Last year, Stanfords Domingue and two colleagues wrote about a hypothetical case study: What happens when a parent tries to use genetic data, like a polygenic score, to make the case that their child deserves additional classroom support?

I dont know that I have good answers to that, he said. But the scenario hints at another serious concern: inequality. Not everyone will be able to afford genetic screening, even when there are meaningful scores for people across ancestries.

Still, researchers are already using the polygenic score to explore long-standing conundrums like why children with very similar advantages follow different trajectories in life.

We are all subject to a big genetic lottery that corresponds to an environmental lottery, von Stumm said. She added that research into the links between genetics and academic attainment could push people to examine fairness in meritocratic societies, given that some people may carry genetic strengths that give them a slight but significant academic advantage, that, in turn, improves other aspects of their lives.

Measuring a persons genetic advantage (or disadvantage) also allows scientists to control for it in their studies. That is, they can better study factors that society can change, such as spending on special programs, compulsory education and school interventions, without having their results biased by a sample of students who are genetically advantaged or disadvantaged.

And researchers can use the polygenic score to assess whether a school has failed students with high potential or if an intervention helped retain children who were otherwise likely to drop out. In the math paper published in February, Domingue, Harden, and their colleagues found that some schools better supported high school students with low polygenic scores than others, ensuring those kids stayed in school.

Harden hopes to see the science applied in ways that emphasize social justice and provide resources to programs that need them: Thats how I think we should be using the polygenic scores if we use them at all.

Genetic Variants Linked to Severe Covid-19 – Physician’s Weekly

Thursday, October 15th, 2020

Genome-wide association study identifies ABO blood protein

The identification of a gene cluster associated with progression to severe disease in patients with Covid-19 strengthens findings from earlier studies suggesting a prominent role for ABO blood group locus in disease severity.

In the genome-wide association study (GWAS) involving patients hospitalized with Covid-19 in Italy and Spain during the local peak of the pandemic, patients with blood group A had an increased risk for progression to severe disease, while patients with blood group O had a lesser risk for progression.

The strongest signal for severe disease, however, was the rs11385942 insertion-deletion GA or G variant at locus 3p21.31, according to researchers from the Severe Covid-19 GWAS Group.

Blood-group specific analysis showed a higher risk for severe disease among patients with blood group A and a lower risk with blood group O.

The groups findings, published Oct. 14 in the New England Journal of Medicine, were originally reported online in June.

In a newly published commentary, researcher Arthur Kaser, MD, of the University of Cambridge Institute of Therapeutic Immunology and Infectious Disease wrote that the genome-wide association study represents a major leap toward disentangling the molecular mechanisms that cause severe Covid-19.

Kaser was not involved with the study.

This genome association study will set directions for research, he wrote, adding that a focus on the immunologic synapse between T cells and antigen-presenting cells appears to be warranted in the search for therapies to address the hyperinflammatory state known as cytokine storm that occurs in some patients with severe Covid-19.

Researchers from the Severe Covid-19 GWAS Group pragmatically compared data from patients hospitalized with severe Covid-19 (defined as respiratory failure), with data from contemporarily recruited blood donors with mostly unknown SARS-CoV-2 status and from historically healthy controls from the same region.

Associations were identified between the risk of developing severe Covid-19 and a multigene locus at 3p21.31 and the ABO blood group locus at 9q34.2.

No association signal was shown for the human leukocyte antigen (HLA) region, which is a regulator of infection immunity and has been suggested as a potential driver of Covid-19 severity.

At locus 3p21.31, the association signal spanned 6 genes: SLC6A20, LZTFL1, CCR9, FYCO1, CXCR6 and XCR1.

The association signal at locus 9q34.2 coincided with the ABO blood group locus; in this cohort, a blood-groupspecific analysis showed a higher risk in blood group A than in other blood groups (odds ratio, 1.45; 95% CI, 1.20-1.75; P=1.48104) and a protective effect in blood group O as compared with other blood groups (odds ratio, 0.65; 95% CI, 0.53-0.79; P=1.06105), wrote Tom H. Karlsen of the University of Oslo, and colleagues from the Severe Covid-19 GWAS Group.

In his editorial, Kaser noted that among the 6 candidate genes at 3p21.31, LZTFL1 might be the most compelling, with the rs11385942 variant and all other fine-mapped association signals that exceeded genome-wide significance located within it.

LZTFL1 is widely expressed and encodes a protein involved in protein trafficking to primary cilia, which are microtubule-based subcellular organelles acting as antennas for extracellular signals, he wrote. In T lymphocytes, LZTFL1 participates in the immunologic synapse with antigen-presenting cells, such as dendritic cells (these cells prime T-lymphocyte responses).

Kaser noted that of the other 5 candidate genes, 4 (CCR9, FYCO1, CXCR6 and XCR1) have roles in T-cell and dendritic-cell function, while SLC6A20 is a transporter with intestinal expression regulated by the SARS-CoV-2 receptor angiotensin-converting enzyme 2 (ACE2).

Earlier research has shown the Covid-19 hyperinflammatory response to resemble secondary hemophagocytic lymphohistiocytosis (HLH), which is a rare and often fatal hyperinflammatory response triggered by autoimmune disorders, certain cancers, and infections.

Kaser wrote that while secondary HLH remains poorly understood, Mendelian-inherited primary HLH points toward CD8+ T lymphocytes, natural killer cells and dendritic cells triggering a cytokine storm involving macrophages.

Other shared features between secondary HLH and severe Covid-19 are cytopenia, hyperferritinemia, disseminated intravascular coagulation, acute respiratory distress syndrome, multiple organ dysfunction, excessive expansion of T lymphocytes, and bone marrow histiocytic hyperplasia with hemophagocytosis with aggregates of interstitial CD8+ lymphocytes, he noted.

The Severe Covid-19 GWAS Group concluded that further exploration of the (study) findings both as to their usefulness in clinical risk profiling of patients with Covid-19 and toward a mechanistic understanding of the underlying pathophysiology, is warranted.

In his commentary, Kaser concluded that the clinical success of treating Covid-19 patients on mechanical ventilation with the corticosteroid dexamethasone provides strong evidence that death may be caused by a late hyperinflammatory phase.

A therapeutic agent that converts severe Covid-19 into a manageable, nonfatal infection would render this pandemic a lesser concern, he wrote.

Because it is impossible to predict mechanisms straight from genomic coordinates, experimental testing of the biology of implicated genetic risk pathways is a route, albeit a potentially challenging one, toward that goal.

An evolutionary jolt helped cattle to spread across Africa. Now genetics must make them more productive – The Conversation Africa

Thursday, October 15th, 2020

African cattle breeds are astonishingly diverse, and often quite beautiful. They range from the dark-red Ankole of southern Uganda, with their massive heat-dissipating horns, to the Boran which thrive in the dusty plains of northern Kenya, to Ethiopias sturdy Mursi cattle, with their prominent shoulder humps and hanging dewlaps. The Kuri that graze on the grasses of Lake Chad are adept swimmers; the Red Fulani can trudge vast distances along the margins of the Sahara; and the famously disease-resistant Sheko inhabit tsetse fly-infested forests of southwest Ethiopia.

All billion or so cattle today descend from ancient aurochs, an extinct species of wild cattle that once inhabited large swaths of Eurasia. These cattle were domesticated on at least two distinct occasions approximately 10,000 years ago during the Neolithic era: once in south Asia leading to the zebu or humped cattle and the other in the Middle East leading to the taurine or humpless cattle.

In Africa, the oldest archaeological evidence of domestic cattle dates back to between 6000 and 5000 BC in western Egypt. These taurine cattle, initially confined to the Saharan-Sahelian belt, eventually reached isolated pockets of land in West and East Africa.

Africas cattle today have adapted to the climate, forage conditions, diseases and pests prevalent in their habitat. The individuals best adapted to their environments were more likely to survive and reproduce. They were also more favoured by people. Over time this led to different breeds and species.

Today there are an estimated 800 million livestock keepers across the continent. Cattle provide nutritious, calorie-dense food, much-needed income, and nitrogen-rich manure for replenishing soils. There are few regions of Africa where cattle do not play a central role, both economically and culturally.

But it was not always this way. My colleagues and I from the International Livestock Research Institute (ILRI) recently published a paper detailing how African cattle acquired their adaptive capacities.

Sifting through the DNA of 16 indigenous African breeds, we discovered a thousand-year-old event in which the worlds two main subspecies of cattle namely taurine and zebus mixed. This allowed African cattle after spending thousands of years confined to certain regions in Africa to diversify and spread across the continent.

Our findings help to explain how African cattle spread throughout the continent. But since they were selected and bred for resilience, African cattle never became as productive, in terms of meat or milk, as breeds in more temperate climates. Our hope is that, by studying the history hidden in indigenous cattle genomes, we can help guide efforts to breed for productivity without losing the breeds native resilience and sustainability.

Our new genome sequencing work revealed that, about a thousand years ago, pastoralist herders in the Horn of Africa began breeding the Asian zebu cattle with local taurine breeds.

The zebu offered traits that allowed cattle to survive in hot, dry climates. The taurine traits provided cattle with the ability to endure humid climates, where vector-borne diseases that affect cattle, like trypanosomiasis (or sleeping sickness) are common.

This event, which we dubbed an evolutionary jolt, allowed African cattle after spending thousands of years confined to a shifting patchwork of sub-regions in Africa to spread across the continent and flourish into the breeds we see today.

But this resilience came at a cost. African cattle are often not as productive in terms of growth rates, meat or milk as their European and American cousins. Canadian Holsteins, for example, can deliver 30 litres of milk per day, several times what most African breeds are capable of. Traditional Ethiopian Boran, for example, produced only four to six litres of milk per day.

Today scientists at ILRI, in partnership with governmental institutions in Tanzania and Ethiopia, are again trying to deliver an evolutionary jolt to Africas cattle. This time, however, they want to speed up the evolutionary clock by identifying genetic markers that signal both adaptability and productivity. Screening embryos for these markers could help scientists replicate in the lab the slow work of evolution by favouring the traits that most benefit farmers.

Earlier efforts to improve cattle productivity on the continent focused on importing cattle breeds from elsewhere, without adequately recognising African breeds unique resilience. Nearly, all these attempts have failed or resulted in crossbreeds with both adaptability and productivity diluted.

This time, we are focusing on sustainable productivityproductivity that builds on rather than disregards the resilience of indigenous African breeds.

But while we have new tools and shortcuts which enables scientists to analyse vast swaths of genetic data and decide which breeds could work well together, there are some lessons we should still draw from the first evolutionary jolt.

The first is that we shouldnt be overly concerned about crossbreeding. Because of a sense of national pride and wanting to conserve indigenous African cattle breeds, there is at times a tendency on the part of some to treat them as iconic, untouchable manuscripts.

This ignores the long tradition of crossbreeding practised by African livestock farmers and pastoralists they were (and still are) constantly mixing and matching breeds to select the animals best suited to their needs.

Another lesson is that, as scientists experiment and cross-breed, it is vitally important to remember that the local breeds have adaptations not all of them immediately obvious (a tolerance for episodic drought, for example) that have enabled their success. It is important that we do not lose those adaptive traits in the randomness of crossbreeding.

This will take innovative crossbreeding programs that incorporate scientists, government ministries, private partners and farmers to ensure the conservation of genetic information across the long life cycle of cattle generations.

And finally, its essential to include the practical, accumulated experience of pastoralists in these processes.

Nurse advises Rotary of the benefits of genetic testing – El Dorado News-Times

Thursday, October 15th, 2020

The El Dorado Rotary Club hosted Tammy McKamie, a genetic certified nurse at the Christus St. Michael Health System in Texarkana, on Monday at their regular meeting, where she spoke about the health benefits of genetic testing.

McKamie, who has worked as a medical professional for nearly 40 years, is the only credentialed genetic certified nurse in Texas, and also serves patients from Arkansas. On Monday, she discussed her specialization in genetics and the role ones genes may play in determining whether they develop cancer during their lives.

While 90% of those who develop cancer do so because of environmental and lifestyle factors, such as smoking or being exposed to carcinogenic chemicals, McKamie said some people are at a heightened risk due to genetic factors.

Almost every person is born with 23 pairs of chromosomes, half of which are inherited from their biological mother and the other half of which are inherited from their biological father.

On each one of these chromosomes, there are thousands of genes. If I add up all the genes in this DNA, were going to have about 20,000 genes, and each one of those has a purpose, McKamie said.

Some of those genes purposes are to protect the individual from developing cancer, she said, a medical breakthrough that was discovered in 1994 during research for the Human Genome Project.

God gave us genes to protect us from cancer, McKamie said. We have two of each gene that theyve discovered so far. One gene may protect you from multiple cancers, so if ones defective, you may be at risk for multiple cancers.

Rotarian Art Noyes asked whether genetic predisposition to cancer may have been related to actress Angelina Jolies decision to undergo a double mastectomy (breast removal) several years ago.

Yes, Angelinas mother had ovarian cancer, so she had this genetic testing years ago, McKamie said. She did the genetic testing and she had a genetic mutation in one of these genes. Angelina had never had cancer, but she had the genetic predisposition toward it.

In Jolies case, McKamie said, there was likely a mutation of the BRCA 1 or 2 gene, which can heighten ones susceptibility to several types of cancers, including breast cancer, ovarian cancer, prostate cancer, colorectal cancer and other types.

For those who opt not to undergo preventative surgeries, like Jolies mastectomy, knowing of any genetic defects can still help medical professionals that care for them, since they will be aware of their increased risk level. Those who do have a genetic predisposition to some types of cancer should undergo earlier and more frequent screenings so that any cancer that does develop can be treated sooner, McKamie said.

If you started out with this defect, we would not wait til 40 (years old) to do a mammogram we would start much earlier, she said. Everybody knows that if you detect cancer early, youre more likely to survive it.

McKamie said a defect in the BRCA 1 or 2 gene can heighten a womans risk of developing breast cancer significantly. For someone without a gene defect, the risk at 40 years old is about 0.5%; at 50 years old, about 2%; and at 70 years old, about 7%. For a woman who does carry a hereditary risk, the likelihood that they will develop breast cancer by age 40 increases to 10 to 20%, depending on which BRCA gene the defect is in; by age 50, the risk is 33 to 50%, and by 70 the risk is 58-87%, McKamie said. For men, the risk of breast cancer increases from 1% for the general population to 7% for those with a genetic defect.

People take it for granted that everythings working but if you knew that one of these was defective and you were at a higher risk for cancer, you might be more healthy, more conscious, McKamie said.

At Christus St. Michael, McKamie offers consultations for those who would like to undergo genetic testing to determine whether they might be at a heightened risk for developing cancer. First, she will take a detailed family medical history and explain to her patient how ones genes might increase their risk for cancer. Following that, she will draw one tube of blood from the patient and send it to a laboratory, with a typical turnaround time of two to three weeks, she said.

This testing is now even evolved to the point to where if you have cancer, the physicians will use it to determine the best type of drug to use to treat you, McKamie said. I get a lot of consults from our cancer physicians and oncologists because they need to know what type of drug to use to treat this person.

McKamie noted that Medicare pays 100% for this sort of genetic testing, and most other medical insurance companies follow their lead; additionally, should any out-of-pocket costs emerge once a patients sample reaches the testing lab, a representative from the lab will call the patient to ensure they still want the testing done.

Before a patient comes to Texarkana for a screening, McKamie will screen them over the phone to ensure they will qualify for coverage for the genetic testing, she said. Those who are interested in a consult can contact her at 903-614-2654 or [emailprotected]

[Cancer diagnostics and treatment] just really evolved, and it continues to evolve, McKamie said. This is the way of the future now.

Focusing on the Future of Genetic Testing in Oncology – OncLive

Thursday, October 15th, 2020

Germline genetic testing is essential in order to identify optimal treatments for patients with cancer, as well as detecting inherited mutations via cascade testing that could affect family members, according to John M.Carethers, MD, MACP, who emphasized that improvements to genetic testing technology and testing costs has increased not only the accuracy of, but access to these assays.

The technology in sequencing has moved from the old gels to capillary to ChIP [chromatin immunoprecipitation]-based, and has revolutionized the way we approached it. The depth of [genetic testing] coverage [has evolved], said Carethers. Sequencing technologies totally revolutionized this [process].

He added, There are some unusual situations in which additional technologies have to be used to figure out some of the ones that typical ChIP technologies don't fully explain. That has markedly changed the way we approach [testing] these days.

In an interview withOncLiveduring the 2020 Institutional Perspectives in Cancer (IPC) webinar on Precision Medicine, Carethers, a professor of Internal Medicine and Human Genetics at the University of Michigan, discussed recent developments in multi-gene panel testing.

OncLive: How are predictive and somatic genetic tests being utilized in clinical practice?

Carethers: In terms of germline testing, the benefit is knowing which disease you carry, and that information can also spread to other family members to understand whether they [are at an increased risk of getting a cancer diagnosis]. Sometimes, at least in my experience, [germline testing] does alleviate some anxiety. Some people get more anxious once they know they have a germline mutation, but in general, it does at least explain the reason why they're seeing certain diseases in the family. Thats the general benefit for germline testing.

The benefit of somatic testing is knowing the type of mutations that occur in the tumor; there may be a therapeutic drug or compound that is in current use that could benefit the patient. For instance, I had a patient with unresectable esophageal cancer. She was dying and her esophagus was almost completely obstructed with the tumor. She had a feeding tube put into her stomach and lost a lot of weight; she was literally counting out the days until she died. With some thought, we decided to take a sample of the tumor and do somatic testing.

She had some mutations that werent typically found in esophageal cancer, and we did have drugs [to treat her]. She was actually put on those drugs and the tumor shrunk dramatically to the point that she could eat again, she gained weight, and she lived another 5 years. Normally, she wouldn't have lasted more than a few months. The benefits of somatic testing is understanding the genetic makeup of the tumor in which you might be able to use some compounds that exist to benefit the patient. Thats the real goal of somatic testing.

There is an unusual situation for somatic testing, as well. For instance, in colon cancer, we know about Lynch syndrome, but there is also a Lynch-like syndrome. In Lynch-like syndrome, there is no germline [mutation], but the tumor has 2 somatic mutations of a mismatch repair deficient tumor. They can look like a Lynch syndrome tumor, and maybe even behave a little bit like a Lynch syndrome tumor, but they're really not caused by a germline mutation. Sometimes, somatic genetics can help us understand tumor genesis as well as ways to treat the tumor.

What changes have we seen recently in multigene panel testing? How are test results interpreted and how do they help guide treatment strategies?

There are patients who will walk in with the classic phenotype and then there are patients walking in who don't have the classic phenotype, yet they carry that mutation in the same gene. Multigene testing allows us to account for phenotypic variation.

Someone may walk in with colon cancer, the next person in the family might walk in with endometrial cancer, and the next person in the family may walk in with a skin tumor, but they all line up with the same mutation in Lynch syndrome. However, if you saw the skin tumor first, would you have thought of Lynch [syndrome]? [What about] if you saw the endometrium or the colon cancer? It depends on the specialty and the type of disease presentation they show up with. In many cases, though, the disease could be subtle.

For instance, there was a family I followed, which comprised the grandmother, mother, and daughter. The grandmother, who was well into her late 60s, had a Lynch syndrome mutation and got her colon removed appropriately. The mother was in her 40s with no cancers, but the daughter who was 21, developed colon cancer. It looked like it skipped a generation, yet, they all carry the same mutation. There's phenotypic variation, even with this exact same mutation in the family, because we're all genetically different to some, so there's probably modifiers and other things going on. However, if I can see that in this one family who I know [harbor that specific] mutation [then I know that] if multiple people walk into the clinic and have variations in their family histories and in their personal history of cancer, that we are seeing a wide phenotypic variation.

Now, instead of testing 1 gene at a time, we will test 30 or 50 genes at a time, and you can pick up some of these less penetrant genes that are causing the phenotypic variation. Sometimes there are major penetrant genes in these families.

What other barriers to germline testing need to be addressed?

We're always learning. Every year or so we add a few more genes to our repertoire and then, maybe they get on some of these panels. E3 ubiquitin ligase WWP1 is associated with PTEN hamartomatumorsyndrome, which is not on any panels, but the paper was published in the New England Journal of Medicine. We keep learning as we discover more and more of these genes. The more genes that we find tend to occur in less and less people, based on our current knowledge, but some of these patients present with these rare phenomena.

We're also finding out that some of these mutations arent specifically a change in the DNA sequencethere are methylation, or rearrangement, or even a deletion. You have to use other techniques in addition to sequencing to figure those families out or those families will be left in the lurch.

The downside of doing multigene panel testing is that now, if you push for more whole-exome and whole-genome sequencing, we have a lot more variants. One commercial lab got [results] back to me 2 months ago from a patient we had tested 4 years ago. They said, We finally have enough people [where we could determine that] his variant is not significant. It was good news. We are now more sure of variants because they now have more families in their database at the commercial lab. Sometimes it takes years to figure it out, unless we have functional analysis for all variants. Thats a big challenge right now.

Where do you hope to see the future of genetic testing head?

In a good way, genetic testing will probably [have a lower] cost and there [will be an] ease of doing it [with] whole-exome and whole-genome sequencing. It will even overtake panel testing over time because the machines are better and faster. The key, though, is having a database that you can go back and forth and analyze. Youre going to need the analytics and tools. What happens with the patient? Do I carry this [information] on a flash drive? Is it in a database I have to have access to?

It's not an easy answer and I'm not sure if the health system that a particular patient goes to is going to store all this information3 billion base pairs of informationand go back to it each time. Each place is going to have to have the right analytic tools to go back and [retrieve that information]. There are going to be some challenges with that, even though that's the way the technology is going.

The more challenging pieces [are related to] direct-to-consumer (DTC) testing. You don't always know what you're getting on those tests. We can test you for common diseases, such as diabetes and hypertension, but we also test you for BRCA1/2. In reality, very few of the DTC [tests] are doing sequencing or panel testing like we do clinically. Many of them are using single nucleotide polymorphisms (SNPs) that give you a suggestion. Many of these start from ancestry companies,and they recently moved into [testing for] these diseases because people are interested. I don't blame them for doing this, but the information they give might only [include] a fraction of the actual disease variants. If someone finds an SNP in BRCA1/2 or Lynch syndrome, you might need to see a doctor. [Based on your family history or phenotype,] we may have to send a ChIP test to verify [the results].

In some cases, people will test just to be curious, and they think they're going to have something, but there is zero evidenceno personal history and no family history. There are going to be some challenges with the DTC [testing] because we don't always know the type of test theyre getting and the information is not going to be as precise and could present challenges in the clinics. Some people are going to get upset because we're going to say, No, you don't need testing, or [patients will ask], Why does this test say I might have it but your test says I don't? We have to explain all this and those are going to be challenges.

What else would you like to add regarding the evolution of genetic testing?

There is phenotypic variability in the presentation of many of these syndromes. The standard now is multigenetic panel testing to try to assuage the phenotypic variation; we do pick up [genes in] people who we didn't necessarily think had that disease. I've been surprised too many times, so I'm not surprised anymore. A lot of these inherited conditions have phenotypic variability. If you have any suspicion or your primary care physician has any suspicion, feel free to send [a test] to our clinic because we can investigate that and do testing that's relatively cheap if there's a good cause to investigate that. It may save their life and the lives of their loved ones.

Study will investigate the genetic impact of escaped farmed salmon – The Fish Site

Thursday, October 15th, 2020

The study has been launched in response to a recent escape of farm-raised salmon and will be managed by the wild-fish conservation body Fisheries Management Scotland, supported by scientists from Marine Scotland Science, and funded by Mowi Scotland.

The multi-year study of 115 sites aims to confirm wild salmons current genetic profile and to track for the potential of genetic changes should interbreeding of farmed and wild salmon occur.

In late August, Mowi Scotland confirmed that 48,834 farm-raised salmon escaped from its Carradale farm in the Firth of Clyde after it became detached from its seabed anchors during a combination of strong weather events.

Since the escape, Fisheries Management Scotland has been working with member District Salmon Fishery Boards and Fisheries Trusts, as well as angling associations, to monitor the situation and mitigate where possible. Escaped farmed salmon have been caught by anglers in multiple rivers across Loch Lomond, Ayrshire, Clyde, Argyll and in rivers in north-west England.

The priority for Fisheries Management Scotland and their members has been to ensure that any farmed fish are removed from the rivers, humanely dispatched, and scale samples submitted to enable accurate identification, and Mowi has committed to support these actions.

Dr Alan Wells, chief executive of Fisheries Management Scotland, said: We are very disappointed that this escape has occurred. The Carradale North farm is a new development, and we are all agreed it is not acceptable for such escapes to occur. It is crucial that lessons are learned, and that appropriate steps are taken to avoid such escapes happening in future.

We have welcomed Mowis commitment to work with us and to fund a comprehensive genetics study that will help us better understand the potential impacts. We will continue to engage with the industry and regulators, with a view to improving the situation for wild salmon and sea trout.

Ben Hadfield, COO of Mowi Scotland, said: I would like to thank Fisheries Management Scotland and their member District Salmon Fishery Boards and Fisheries Trusts for their efforts to remove these fish from rivers across the Firth of Clyde, and apologise for any disruption and concern this escape has caused all those with an interest in wild salmon. We have learned the root cause of the escape system anchor lines crossing and resulting in friction failure and acknowledge our responsibility to quickly learn from this event to prevent it from occurring again.

Polly Burns, aquaculture interactions manager at Fisheries Management Scotland, added: We would like to thank anglers for their continuing efforts to capture and report farmed fish entering our rivers. We have received about 150 reports of farmed fish captures from a range of rivers both within and out with the Firth of Clyde and we continue to urge anglers to report catches of farmed fish, using the reporting system on our website.

The Health and Welfare of Atlantic Salmon course

It is vital that fish farm operatives who are responsible for farmed fish are trained in their health andwelfare. This will help to ensure that fish are free from disease and suffering whilst at the same timepromote good productivity and comply with legislation.

This new and comprehensive study of genetic introgression aims to add to the understanding of one of the potential pressures on Scotlands wild salmon, which are approaching crisis-point. The Scottish Government has identified a range of high-level pressures on wild salmon to also include: over-exploitation, predation, invasive species, habitat loss and inshore commercial fisheries.

Unraveling the Impact of Lifestyle, Genetics on MS – Managed Markets Network

Tuesday, September 15th, 2020

Obesity and metabolic syndrome

Adiposity obesity, particularly when it begins in childhood and late adolescence, was identified as leading to a 2-fold risk of developing MS in one study, according to Ruth Ann Marrie, MD, PhD, FRCPC, director of the Multiple Sclerosis Clinic at the University of Manitoba. Central obesity, or visceral adipose fatty deposits in the abdominal area, is a key component of metabolic syndrome, a cluster of abnormalities that includes hypertension, dyslipidemia, and insulin resistance and is linked to a higher risk of cardiac disease and diabetes.

In the Nurses Health Study, which examined risk factors for chronic disease, women with a body mass index (BMI) of 30 or more had a 2-fold increased risk of subsequently developing MS. And a study using data from the Copenhagen School Health Records Register found that children aged 7 to 13 years with a BMI equivalent to 30 in adults had an increased risk of developing MS later in life.

Obesity is more common even before MS diagnosis, Marrie said. In an effort to look at other aspects of metabolic syndrome, researchers used Canadian claims data of about 20,000 individuals with newly diagnosed MS and found that by the time of diagnosis, more than 15% had hypertension and nearly 10% had dyslipidemia.

There is also evidence that obesity and components of metabolic syndrome are associated with longer diagnostic delays, greater disability at diagnosis, as well as an increased relapse rate and accelerated disability progression. One key question she said, is whether treating metabolic syndrome might improve MS outcomes and multiple sclerosis.

In one small, nonrandomized cohort study of 50 individuals with MS, obesity, and metabolic syndrome, they were treated either with metformin or pioglitazone, or they declined treatment.

Before treatment, researchers measured the number of newer enlarging T2 lesions in the 24-month period before intervention as well as gadolinium-enhancing lesions; all 3 groups looked similar.

After treatment with either metformin or pioglitazone, the number of newer T2 lesions as well as gadolinium-enhancing lesions dropped over 24 months. Patients who declined treatment did not see a decrease.

I think the growing body of evidence suggests that clinical trials are needed to really test whether treating obesity and metabolic syndrome may improve outcomes in MS and to test whether we need to be using different strategies for managing disease-modifying therapy, including dosing in individuals who are obese or extremely obese with multiple sclerosis, Marrie said.

Smoking and genetics

Another presentation focused on the interactions between modifiable risk factorsnamely smokingand genetics.

People with a genetic susceptibility to the disease may be at a substantially increased risk of developing MS if youre exposed to certain environmental factors, said Anna Hedstrm, MD, PhD, from the Karolinska Institute Stockholm, Sweden in the Department of Clinical Neuroscience.

Smoking and the chemicals from tobacco creates a cascade of problems, including systemic inflammation, local inflammation in the lungs, oxidative stress, damaged neural tissue, and epigenetic changes.

Smoking increases the risk of MS by about 50%, she said, with men more affected than women; in addition, there is also a dose response relationship between the accumulated dose of smoking and the risk of developing the disease.

In 2005, the Karolinska Institute began a study called the Epidemiological Investigation of Multiple Sclerosis, which uses the countrys national MS registry. As an ongoing study, it now includes 9000 cases and 12,000 matched controls.

In 2011, Hedstrm and colleagues published a study that found a significant interaction between 2 genetic risk factors and smoking: HL ADRB1*15, the key genetic risk factor for MS, and HLA A*02, the absence of which carries a reduced risk of MS. The research looked at the interaction of these genes in both smokers and non-smokes.

Smokers with both genes had an odds ratio (OR) of 13.5 (8.1-22.6) for MS, compared with nonsmokers with the same makeup.

Compared with non-smokers with neither of the genetic risk factors, the OR for smokers without genetic risk was 1.4 (0.9-2.1); the OR for non-smokers with both genetic risk factors was 4.9 (3.6-6.6).

Among those with both genetic risk factors, smoking increased the risk by a factor of 2.8 in comparison with a factor of 1.4 among those without the genetic risk factors.

Passive smoking (ie, never smokers exposed to second-hand smoke) also increases MS risk (OR 1.3-1.6) and the risk increases along with the length of exposure, she said.

Similarly, exposure to organic solvents, she said, also raises the rise of MS in people with the same genetic profile.

MS and Epstein-Barr virus (EBV) infection

No virus has been discovered as a cause of MS, but the hypothesis that a virus may be involved in MS has been around for some time, said Kassandra Munger, ScD, of the Department of Nutrition in the Harvard TH Chan School of Public Health. Current knowledge, she said, points to Epstein-Barr.

From environmental risk factor perspective, MS is likely a rare complication of Epstein-Barr virus infection, with risk further modified by inadequate vitamin D levels, being overweight or obese in early life and cigarette smoking, she said.

Early studies attempting to look at the issue through antibody testing could not determine if EBV infection proceeded MS or if it was a complication.

Using blood samples collected by the Department of Defense of US military members, Munger and colleagues found preliminary evidence that EBV infection does happen before MS. They identified 305 MS cases and 610 matched controls. In cases where serum samples were collected before the onset of MS symptoms and measured EBV titers, they found that 38 were EBV negative at the time they went on active duty. During follow up, up until MS onset, 20 of the 38 became EBV positive. Eighteen remained EBV negative and did not develop MS.

This is a preliminary finding that needs to be replicated in a larger study, she said.

When ‘bones and stones’ are not enough: Genetics fills in the blanks in the story of human evolution – Genetic Literacy Project

Tuesday, September 15th, 2020

In recent years, a field that has traditionally relied on fossil discoveries has acquired helpful new tools: genomics and ancient DNA techniques. Armed with this combination of approaches, researchers have begun to excavate our species early evolution, hinting at a far more complex past than was previously appreciatedone rich in diversity, migration, and possibly even interbreeding with other hominin species in Africa.

To piece together that story, we need information from multiple different fields of study, remarks Eleanor Scerri, an archaeologist at the Max Planck Institute for the Science of Human History in Jena, Germany. No single one is really going to have all the answersnot genetics, not archaeology, not the fossils, because all of these areas have challenges and limitations.

[I]t was the advent of genetic research that showed unequivocally that populations outside of Africa descended from a single population in Africa. But the story had a twist: intwogroundbreakingstudiespublished in 2014, researchers compared ancient DNA extracted from Neanderthal bones and compared it with modern-day people, and found that 2 percent of the average European genome is Neanderthal in origin. Our species originated in Africa, but interbred with hominins outside of it.

These findings, and many since, have highlighted the power of genetics in resolving questions about human ancestry that fossils alone cannot.

Minority-owned biotech startup Acclinate Genetics secures investment to expand diversity in clinical trials – GlobeNewswire

Tuesday, September 15th, 2020

Acclinate Genetics Co-Founders Tiffany Jordan-Whitlow and Del Smith

Huntsville, Alabama, Sept. 15, 2020 (GLOBE NEWSWIRE) -- Racial and ethnic minorities make up 40 percent of the U.S. population. But in clinical trials, minorities often account for as little as two percent of participants. As a result, there are many examples of commonly prescribed pharmaceuticals that are less effective or have negative side effects due to a persons race and ethnicity.

This is a problem that needs to be addressed, saysDel Smith, co-founder and Chief Executive Officer of Acclinate Genetics. It only exacerbates the health inequalities were already dealing with in America and around the world. We believe that diversifying genomic research and clinical trials to include more representation and diversity increases knowledge about health issues and makes a difference in personalized healthcare for all.

Smith and co-founder of Acclinate Genetics Tiffany Jordan-Whitlow have both been personally impacted by the lack of minority representation in medicine. Their company helps biopharmaceutical companies and contract research organizations increase minority and ethnic participation in research and trials. With a platform that protects privacy, the company utilizes machine learning and predictive analytics to ensure selection of more diverse participants. Acclinate creates value by decreasing the overall cost of drug development, increasing the speed of drug approval, integrating with virtual clinical trials and contributing to the discovery of new drugs.

Acclinate Genetics recently gained backing from Bronze Valley, a Birmingham-based early stage venture investment platform dedicated to supporting high growth, minority-owned businesses. The partnership makes Acclinate Genetics the first bio company to join Bronze Valleys portfolio.

We are proud to announce our partnership with Bronze Valley, and we are grateful for their support and confidence in Acclinate Genetics position for future growth. says Jordan-Whitlow. With forward momentum, Acclinate remains focused on helping diverse individuals make informed decisions about genomic research, clinical trial participation and their overall health.

Addressing longstanding inequities in research and clinical trials also presents business opportunities. Currently, the clinical trial patient recruitment market is a $3.4 billion business, a figure projected to grow to $5.3 billion by 2030.

Acclinates Smith says that he and Jordan-Whitlow have followed the philosophy of applying sound business principles to making positive social impacts. As Acclinate continues to grow and scale, the company seeks investors and partners, who honor that same philosophy, to come alongside them.

About Acclinate Genetics

California Enacts the Genetic Privacy Information Act | Newmeyer Dillion – JD Supra

Tuesday, September 15th, 2020

With the focus of personal privacy increasing, it is unsurprising that additional laws are being proposed to increase privacy rights, including the California Privacy Rights Act initiative on the ballot this upcoming November. More immediately, the California legislature passed, and Governor Newsom signed, the Genetic Information Privacy Act ("GIPA"). GIPA specifically targets biometric information, due to the increase of genetic tracing services, like 23andMe and This law pertains to adding more protections to genetic privacy. Many questions arise following the passage of GIPA, such as what businesses are affected? What, if any, penalties or causes of action exist under this new law? How does this law work alongside the CCPA?


The law requires notices and actual, express consent from consumers for direct-to-consumer genetic testing companies, and any other company that collects, uses, maintains, or discloses information collected from biometric samples, or from any other element concerning genetic material (i.e. genes). Regarding the express consent provision in particular, this requires that consent is provided for: (1) the use of data through the genetic testing product being provided, for those specific purposes; (2) the storage of the consumer's biometric sample after testing is complete; (3) each use of the genetic data or sample beyond what was originally intended; (4) each transfer or disclosure to a third party other than service providers, including that third party's name; and (5) any marketing based on the genetic data. In essence, unless a consumer explicitly opts in, these companies cannot store, use, or market based on the genetic information.


The penalties for not following GIPA are akin to those for the CCPA, with a $1,000 fine, plus court costs for negligent violations, and $10,000 for willful violations. Furthermore, unlike the CCPA, this law does include a private right of action, as it allows a person who has suffered injury in fact, or has lost money or property, as a result of a violation. In essence, this increases the damages for a company which fails to reasonably secure genetic information from data breaches, though plaintiffs may have difficulty showing that money or property was lost due to the exposure of their genetic information, unlike the CCPA, which implements statutory damages just for the breach occurring.


Regarding the CCPA, both laws will be in effect, and these companies would be obliged to provide additional notices in addition to those required under the CCPA. Furthermore, they both would protect the same information, as the CCPA does protect biometric data, which would largely overlap with the protections of the genetic information under GIPA. GIPA and the CCPA also both require that reasonable security is utilized to protect the consumer's genetic information. However, GIPA also goes further, in requiring that reasonable security is taken to prevent unauthorized destruction as well. Furthermore, it is noteworthy that GIPA relies on the same "reasonable security" language as the CCPA.

Ultimately, GIPA places stricter requirements on genetic testing companies, such that they will have to be more transparent with consumers, and it may serve as a model for future changes to the CCPA. For instance, GIPA will require more click-wrap agreements and additional changes to items like Terms of Use agreements, to ensure that users agree to each use of the genetic data.


For businesses subject to GIPA, reviewing, adjusting and implementing additional consent measures to a website should be paramount, as well as reviewing and updating the privacy policy once more in order to make sure that all notices are present. Furthermore, reviewing current security measures and processes is equally important, due to the more stringent requirements on the restrictions against unauthorized destruction of information.

Ultimately, the biggest change to genetic testing companies under GIPA may be an increased reliance on consumer accounts permitting consumers to login, see, and manage their data in order to give the individualized consents, an increased reliance on click-wrap agreements requiring that consumers scroll through, read, and accept actions by the company before the company takes them, or a combination of the two.

For other businesses, GIPA provides an opportunity to implement and utilize stricter privacy guidelines, and implement them as a potential benefit to consumers, as GIPA requirements largely surpass those under the CCPA.

Craving the Sun? Twin Study Finds It May Be Genetic –

Tuesday, September 15th, 2020 Interview with:

Dr Mario FalchiHead of Bioinformatics for the School of Life Course SciencesDepartment of Twin Research & Genetic EpidemiologyKings College London What is the background for this study?

Response: The relationship between sun exposure and health is a double-edged sword, on one side there is the beneficial effect of vitamin D production and on the other the increased risk of skin cancer, depending on length and frequency of exposure, and on the individual skin type.

Despite public health campaigns, changing sun-seeking behaviour seems to be challenging for some people, even for those with a familial or personal history of skin cancer. Previous investigations have suggested that exposure to UV could be addictive. What are the main findings?

Response: We investigated the sun seeking behaviour of 2,500 twins from the TwinsUK cohort, finding that identical twins tend to share a more similar attitude towards sun exposure compared to fraternal twins. Sun seeking seems to be heritable and significantly influenced by genetics. To identify the genes involved, we performed a genome-wide association study of sun seeking behaviour in 260,000 volunteers from the UK Biobank and the US Nurses Health Studies and Health Professionals Follow-up Study, which highlighted five significantly-associated genetic loci. These loci are enriched for genes expressed in the central nervous system, and that have been previously associated with behavioural traits, cognitive function, and addiction. Interestingly, one of these genes has also recently been associated with vitamin D levels What should readers take away from your report?

Response: Sun seeking behaviour is influenced by genes involved in neuropsychological traits and addiction. This should be taken into account to improve the efficiency of public health campaigns aimed at reducing sun exposure and incidence of skin cancer. What recommendations do you have for future research as a result of this work?

Response: Further investigations aimed at understanding the mechanisms of addiction more generally, and the biological pathways involved will help in identifying potential drug targets to tackle and help controlling a number of risky behaviours that have a negative impact on public health.

The Borofka family celebrates another year with their son, who is suffering from a rare genetic disease – KSBW Monterey

Tuesday, September 15th, 2020

The Borofka family celebrated their son JTs second birthday by throwing him a drive-by birthday parade Sunday. JT Borofka has already achieved more obstacles than most kids his age. Suffering with Triosephosphate Isomerase Deficiency, or TPI, this rare genetic disease has been challenging to say the least.Hes weaker, but at the moment hes stable, explained JTs mom, Tara Borofka. We still work with physical therapy. Hes got a little bit better head control. JT is extremely strong and doesnt give up. If theres a toy that is a little too far, he will reach for it even if he has to fall over.And just like JT, his doctors in Pittsburgh arent giving up either.The next step is to go through all the compounds they have found that could possibly be a cure, explained Jason Borofka, JTs dad.Michael Palladino, Professor of Pharmacology and Chemical Biology at the University of Pittsburgh School of Medicine said those compounds will need to be tested.We can test them first in a mouse model, explained Palladino. If you can show that not only did it work in JTs cell. We have JTs cells to test these drugs in, but when we put it in an animal model with his same mutations, that that animal model improves as well.The process can take anywhere from 8 months to 3 years, but while the Borofkas wait for the cure, theyre focusing on celebrating another year with their son.If you would like more information about JT and the researching being done in Pittsburgh, you can visit their website.

Can we stand together and overcome adversity and genetics? – Laurel Outlook

Friday, September 11th, 2020

I would like to refer to the excellent article by Barbara Karst in the Outlook September 3rd edition. I take exception to one statement.

Racism is not an inherent attitude. It has to be taught by someone - parents, grandparents, and others who are racist/ bigoted. This statement brings into play the continuing discussion; does man learn through nurture or nature? Do we only learn from the experiences encountered from the time of conception on, or is there residual knowledge passed on to us via genetics?

I would like to refer you to the works of Dr. E. O. Wilson, major proponent of sociobiology, Robert Ardrey and his four book series, The Nature of Man, and to the work of Dr Raymond Dart after his 1924 discovery of the Australopithecus Africanus. Their assertion is we learn by both nurture AND nature. Dr. Darts bold, blunt and controversial statement is both man and animals retain knowledge through instinct. The strongest instinct being the instinct to survive.

There are many facets to the act of survival. Currently most common is the discussion of the herd instinct, or the social need for community. This need for community is so strong, we use the deprivation of community as a form of punishment. We imprison, or remove from society our criminals. Solitary confinement is not only considered a punishment but has proven to be a form of torture. Religions shun or excommunicate controversial individuals. We instinctually repel or fear that which is new or not understood for it may threaten our survival.

To be succinct, we are all bigots. Strength in numbers, or the herd can provide security. We look alike. We talk alike. We think alike. I will be safe. I will survive and in times of stress, we revert to that which we presume will again protect us.

Ironically, the study of genetics has shown us the necessity for diversity. We have learned the inbreeding of animals and humans can cause numerous physical and mental deficiencies. We can also inbreed our society intellectually. The art of learning is augmented through the nurturing of our young and the continued exploration of creation throughout our lives.

In this time of social and economic uncertainty, will we revert to the herd? Retreat to our embattlements and separate into isolated communities fearful of the unknown? Or do we have the courage and strength of character to stand together in an ever expanding herd and face the unknown? Strength of numbers, nature, expansion of knowledge, nurture, they can work together.

Brighton researchers lead study on genetics and asthma – The Argus

Friday, September 11th, 2020

A STUDY has shown for the first time that genetics may play a part in how well children respond to treatment for asthma.

Researchers at Brighton and Sussex Medical School (BSMS) say their findings indicate that childrens asthma symptoms could be better controlled with personalised treatments.

Dr Tom Ruffles, honorary consultant in paediatric respiratory medicine, worked with a study team led by Professor Somnath Mukhopadhyay, chairman in paediatrics at the Royal Alexandra Childrens Hospital and BSMS.

Dr Ruffles and Professor Mukhopadhyay presented the results from their trial at the virtual European Respiratory Society International Congress.

According to Dr Ruffles, asthma affects one in 11 children in the UK and a child is admitted to hospital because of their asthma every 18 minutes.

He told the conference: Asthma is a common condition in children that causes coughing, wheezing and difficulty breathing.

We have a number of medicines that are generally effective in treating children with asthma, but they dont work equally well for all children.

We think that genetic differences could have an effect on whether these medicines work and thats what we wanted to examine in this study.

Previous research suggests the majority of children with asthma will benefit from standard treatment with a medicine called salmeterol and their regular steroid inhaler.

However about one in seven children have a small genetic difference which means using this medication could actually result in them having more asthma symptoms.

The BSMS study involved 241 young people aged between 12 and 18 who were all being treated for asthma.

Participants were randomly assigned either to receive treatment according to existing guidelines, or treatment according to particular genetic differences their genotype an approach known as personalised medicine.

Children in the personalised medicine group were treated with an alternative asthma medicine called montelukast.

Researchers followed the children for a year to monitor their quality of life, with a score between one and seven according to how their symptoms were and whether their normal activities were limited by their asthma.

They found that for children with a particular gene who were given personalised treatment, they experienced an improvement in their quality of life score.

Professor Mukhopadhyay said: These results are very promising because they show for the first time, that it could be beneficial to test for certain genetic differences in children with asthma and select medication according to those differences. In this study we saw only a modest effect, but this may be partly because the childrens asthma was generally very well controlled and only a few children experienced any serious symptoms during the 12-month period.

Larger trials, with a focus on those with poorer asthma control, may help us determine the true benefit for children of prescribing in this way.

Genetic Links to Drug and Alcohol Use Among Young People With Mental Health Risks – Medscape

Friday, September 11th, 2020

Young people who are genetically predisposed to risk-taking, low extraversion and schizophrenia are more likely to use alcohol, cigarettes, cannabisor other illicit drugs, according to a new University College London-led study.

The researchers say that the findings, published in Addiction Biology, are in line with the notion that people who are more vulnerable to psychopathology or certain personality traits are more inclined to try several types of drugs or use them to 'self-medicate'.

The study used data from the Avon Longitudinal Study of Parents and Children (n=4218) and applied traitstateoccasion models to delineate the common and substancespecific factors based on four classes of substances (alcohol, cigarettes, cannabis and other illicit substances) assessed over time (ages 17, 20 and 22 years). The researchers generated 18 polygenic scores indexing genetically influenced mental health vulnerabilities and individual traits.

The results implicated several genetically influenced traits and vulnerabilities in the common liability to substance use, most notably risk taking (bstandardised, 0.14; 95% CI, 0.10-0.17), followed by extraversion (bstandardised, 0.10; 95% CI, 0.13 to 0.06)and schizophrenia risk (bstandardised, 0.06; 95% CI, 0.02-0.09).

Educational attainment (EA) and body mass index (BMI) had opposite effects on substancespecific liabilities such as cigarette use (bstandardised EA, 0.15; 95% CI, 0.19 to 0.12 and bstandardisedBMI, 0.05; 95% CI, 0.02-0.09) and alcohol use (bstandardisedEA, 0.07; 95% CI, 0.03-0.11 and bstandardisedBMI, 0.06; 95% CI, 0.10 to 0.02).

These findings point towards largely distinct sets of genetic influences on the common versus specific liabilities.

Co-lead author Dr Tabea Schoeler (UCL Psychology and Language Sciences) said: Treatment and prevention programmes that target risk-taking behaviours among young people, while also focusing on adolescents with early signs of schizophrenia, could be beneficial in reducing the risk of developing substance use problems.
