  • China Uses DNA to Track Its People, With the Help of American Expertise - The New York Times
    https://www.nytimes.com/2019/02/21/business/china-xinjiang-uighur-dna-thermo-fisher.html

    Collecting genetic material is a key part of China’s campaign, according to human rights groups and Uighur activists. They say a comprehensive DNA database could be used to chase down any Uighurs who resist conforming to the campaign.

    Police forces in the United States and elsewhere use genetic material from family members to find suspects and solve crimes. Chinese officials, who are building a broad nationwide database of DNA samples, have cited the crime-fighting benefits of China’s own genetic studies.

    To bolster their DNA capabilities, scientists affiliated with China’s police used equipment made by Thermo Fisher, a Massachusetts company. For comparison with Uighur DNA, they also relied on genetic material from people around the world that was provided by Kenneth Kidd, a prominent Yale University geneticist.

    On Wednesday, Thermo Fisher said it would no longer sell its equipment in Xinjiang, the part of China where the campaign to track Uighurs is mostly taking place. The company said separately in an earlier statement to The New York Times that it was working with American officials to figure out how its technology was being used.

    Dr. Kidd said he had been unaware of how his material and know-how were being used. He said he believed Chinese scientists were acting within scientific norms that require informed consent by DNA donors.

    China’s campaign poses a direct challenge to the scientific community and the way it makes cutting-edge knowledge publicly available. The campaign relies in part on public DNA databases and commercial technology, much of it made or managed in the United States. In turn, Chinese scientists have contributed Uighur DNA samples to a global database, potentially violating scientific norms of consent.

    Cooperation from the global scientific community “legitimizes this type of genetic surveillance,” said Mark Munsterhjelm, an assistant professor at the University of Windsor in Ontario who has closely tracked the use of American technology in Xinjiang.

  • James Watson Won’t Stop Talking About Race - The New York Times
    https://www.nytimes.com/2019/01/01/science/watson-dna-genetics-race.html

    It has been more than a decade since James D. Watson, a founder of modern genetics, landed in a kind of professional exile by suggesting that black people are intrinsically less intelligent than whites.

    In 2007, Dr. Watson, who shared a 1962 Nobel Prize for describing the double-helix structure of DNA, told a British journalist that he was “inherently gloomy about the prospect of Africa” because “all our social policies are based on the fact that their intelligence is the same as ours, whereas all the testing says, not really.”

    Moreover, he added, although he wished everyone were equal, “people who have to deal with black employees find this not true.”

    Some scientists said that Dr. Watson’s recent remarks are noteworthy less because they are his than because they signify misconceptions that may be on the rise, even among scientists, as ingrained racial biases collide with powerful advances in genetics that are enabling researchers to better explore the genetic underpinnings of behavior and cognition.

    “It’s not an old story of an old guy with old views,’’ said Andrea Morris, the director of career development at Rockefeller University, who served as a scientific consultant for the film. Dr. Morris said that, as an African-American scientist, “I would like to think that he has the minority view on who can do science and what a scientist should look like. But to me, it feels very current.’’

    David Reich, a geneticist at Harvard, has argued that new techniques for studying DNA show that some human populations were geographically separated for long enough that they plausibly could have evolved average genetic differences in cognition and behavior.

    But in his recent book, “Who We Are and How We Got Here,’’ he explicitly repudiates Dr. Watson’s presumption that such differences would “correspond to longstanding popular stereotypes’’ as “essentially guaranteed to be wrong.’’

    Even Robert Plomin, a prominent behavioral geneticist who argues that nature decisively trumps nurture when it comes to individuals, rejects speculation about average racial differences.

    “There are powerful methods for studying the genetic and environmental origins of individual differences, but not for studying the causes of average differences between groups,” Dr. Plomin writes in an afterword to be published this spring in the paperback edition of his book, “Blueprint: How DNA Makes Us Who We Are.”

  • Most White Americans’ DNA Can Be Identified Through Genealogy Databases - The New York Times
    https://www.nytimes.com/2018/10/11/science/science-genetic-genealogy-study.html

    The genetic genealogy industry is booming. In recent years, more than 15 million people have offered up their DNA — a cheek swab, some saliva in a test-tube — to services such as 23andMe and Ancestry.com in pursuit of answers about their heritage. In exchange for a genetic fingerprint, individuals may find a birth parent, long-lost cousins, perhaps even a link to Oprah or Alexander the Great.

    But as these registries of genetic identity grow, it’s becoming harder for individuals to retain any anonymity. Already, 60 percent of Americans of Northern European descent — the primary group using these sites — can be identified through such databases whether or not they’ve joined one themselves, according to a study published today in the journal Science.

    Within two or three years, 90 percent of Americans of European descent will be identifiable from their DNA, researchers found. The science-fiction future, in which everyone is known whether or not they want to be, is nigh.

    Their results were eye-opening. The team found that a DNA sample from an American of Northern European heritage could be tracked successfully to a third-cousin distance of its owner in 60 percent of cases. A comparable analysis on the MyHeritage site had similar results. (The analysis focused on Americans of North European background because 75 percent of the users on GEDmatch and other genealogy sites belong to that demographic.)

    Some experts have raised questions about the study’s methodology. Its sample size was small, and it didn’t factor in that more than one match is often required to identify a suspect.

    CeCe Moore, a genetic genealogist with Parabon, a forensic consulting firm, also expressed worry in an email that the Science paper may obscure the difficulty involved in puzzling out someone’s identity; it takes a highly skilled expert to build a family tree from the initial genetic clues.

    Still, she said, the takeaway of the study “is not news to us.” In recent months Ms. Moore has been involved in a dozen murder and sexual assault cases that used GEDmatch to identify suspects. Of the 100 crime-scene profiles that her firm had uploaded to GEDmatch by May, half were obviously solvable, she said, and 20 were “promising.”

    “I think it’s a strong and convincing paper,” said Graham Coop, a population genetics researcher at the University of California, Davis. In a blog post in May, Dr. Coop calculated just how lucky investigators had been in the Golden State killer case. He reached a statistical conclusion similar to Dr. Erlich’s: society is not far from being able to identify 90 percent of people through the DNA of their cousins in genealogical databases.

    “This is this moment of, wow, oh, this opens up a lot of possibilities, some of which are good and some are more questionable,” he said.

    In an alarming result, the Science study found that a supposedly “anonymized” genetic profile taken from a medical data set could be uploaded to GEDmatch and positively identified. This shows that an individual’s private health data might not be so private after all.

  • New studies show how easy it is to identify people using genetic databases - STAT
    https://www.statnews.com/2018/10/11/genetic-databases-privacy

    n recent months, consumer genealogy websites have unleashed a revolution in forensics, allowing law enforcement to use family trees to track down the notorious Golden State Killer in California and solve other cold cases across the country. But while the technique has put alleged killers behind bars, it has also raised questions about the implications for genetic privacy.

    According to a pair of studies published Thursday, your genetic privacy may have already eroded even further than previously realized.

    In an analysis published in the journal Science, researchers used a database run by the genealogy company MyHeritage to look at the genetic information of nearly 1.3 million anonymized people who’ve had their DNA analyzed by a direct-to-consumer genomics company. For nearly 60 percent of those people, it was possible to track down someone whose DNA was similar enough to indicate they were third cousins or closer in relation; for another 15 percent of the samples, second cousins or closer could be found.

    Yaniv Erlich, the lead author on the Science paper, said his team’s findings should prompt regulators and others to reconsider the assumption that genetic information is de-identified. “It’s really not the case. At least technically, it seems feasible to identify some significant part of the population” with such investigations, said Erlich, who’s a computer scientist at Columbia University and chief science officer at MyHeritage.

    The Science paper counted 12 cold cases that were solved between April and August of this year when law enforcement turned to building family trees based on genetic data; a 13th case was an active investigation.

    The most famous criminal identified this way: the Golden State Killer, who terrorized California with a series of rapes and murders in the 1970s and 1980s. With the help of a genetic genealogist, investigators uploaded a DNA sample collected from an old crime scene to a public genealogy database, built family trees, and tracked down relatives. They winnowed down their list of potential suspects to one man with blue eyes, and in April, they made the landmark arrest.

    To crack that case, the California investigators used GEDmatch, an online database that allows people who got their DNA analyzed by companies like 23andMe and Ancestry to upload their raw genetic data so that they can track down distant relatives. MyHeritage’s database — which contains data from 1.75 million people, mostly Americans who’ve gotten their DNA analyzed by MyHeritage’s genetic testing business — works similarly, although it explicitly prohibits forensic searches. (23andMe warns users about the privacy risks of uploading their genetic data to such third party sites.)

    “For me, these articles are fascinating and important and we shouldn’t shy away from the privacy concerns that these articles raise. But at the same time, we should keep in mind the personal and societal value that we believe that we are accruing as we make these large collections,” said Green, who was not involved in the new studies and is an adviser for genomics companies including Helix and Veritas Genetics.

    He pointed to the potential of genomics not only to reunite family members and put criminals behind bars, but also to predict and prevent heritable diseases and develop new drugs.

    As with using social media and paying with credit cards online, reaping the benefits of genetic testing requires accepting a certain level of privacy risk, Green said. “We make these tradeoffs knowing that we’re trading some vulnerability for the advantages,” he said.

  • Are Genetic Testing Sites the New Social Networks? - The New York Times
    https://www.nytimes.com/2018/06/16/style/23-and-me-ancestry-dna.html

    At-home genetic testing services have gained significant traction in the past few years. 23andMe, which costs $99, has over five million customers, according to the company; AncestryDNA (currently $69), over 10 million.

    The companies use their large databases to match willing participants with others who share their DNA. In many cases, long-lost relatives are reuniting, becoming best friends, travel partners, genealogical resources or confidantes.

    The result is a more layered version of what happened when Facebook first emerged and out-of-touch friends and family members found one another. Children of long-ago casual sperm donors are finding their fathers. Adoptees are bonding to biological family members they’ve been searching for their entire lives.

    The Genetic Global Village

    Others who have their DNA tested are forming relationships not with specific people, but with their family’s places of origin.

    One example is Leah Madison, 32, an education outreach coordinator for the Desert Research Institute in Reno, Nev. She was planning trips to Peru and Korea when she learned a year and a half ago from 23andMe that her family came from Greece, Italy and the Iberian Peninsula.

    Over the winter she and her father went to the Iberian Peninsula for two weeks. She felt an ineluctable connection to the people as she ate their bread masterpieces, toured buildings by Antoni Gaudí and danced to flamenco music.

    “I had a piece of paper that tells me I’m from Spain,” Ms. Madison said. “But then I went there and I noticed all these people have curly hair, and maybe that is where mine comes from?” Now she feels compelled to visit the other places as well.

    Perhaps the most frustrating reality is when users don’t have any known connections at all. This can happen to people in certain ethnic groups, including Latinos and Asians, that thus far have fewer people using the services and a smaller database.

    “Diversity in genetic research is a global problem,” said Joanna Mountain, the senior director of Research at 23andMe, adding that the company is offering free testing in some countries to begin to rectify that. “The results for Hispanics and Asians aren’t there yet, but they are coming,” said Jenn Utley, a family historian at Ancestry (the parent company of AncestryDNA). “The database keeps growing.”

  • Google Has Released an AI Tool That Makes Sense of Your Genome - MIT Technology Review
    https://www.technologyreview.com/s/609647/google-has-released-an-ai-tool-that-makes-sense-of-your-genome

    DeepVariant was developed by researchers from the Google Brain team, a group that focuses on developing and applying AI techniques, and Verily, another Alphabet subsidiary that is focused on the life sciences.

    The team collected millions of high-throughput reads and fully sequenced genomes from the Genome in a Bottle (GIAB) project, a public-private effort to promote genomic sequencing tools and techniques. They fed the data to a deep-learning system and painstakingly tweaked the parameters of the model until it learned to interpret sequenced data with a high level of accuracy.

    “The success of DeepVariant is important because it demonstrates that in genomics, deep learning can be used to automatically train systems that perform better than complicated hand-engineered systems,” says Brendan Frey, CEO of Deep Genomics.

    The release of DeepVariant is the latest sign that machine learning may be poised to boost progress in genomics.

    DeepVariant will also be available on the Google Cloud Platform. Google and its competitors are furiously adding machine-learning features to their cloud platforms in an effort to lure anyone who might want to tap into the latest AI techniques (see “Ambient AI Is About to Devour the Software Industry”).

  • How to Spend $1,900 on Gene Tests Without Learning a Thing - MIT Technology Review
    https://www.technologyreview.com/s/609103/how-to-spend-1900-on-gene-tests-without-learning-a-thing

    But instead of air purifiers, bacon toasters, and other electronic gadgets that no one really needs, people with money to burn can spend $149 on a scarf whose pattern is personalized using their genes, DNA diet apps, or even genetically influenced wine recommendations.

    Eric Topol, an influential heart doctor and geneticist at the Scripps Research Institute in La Jolla, California, says he’s had enough. To Topol, too many of these apps amount to genetic astrology. “The data has no basis. It’s pseudoscience—complete, utter nothing,” he says. He calculated that a consumer could spend $1,900 on 17 apps and learn almost nothing of value.

    Earlier this year, the U.S. Food and Drug Administration signaled that it would unwind what had been a de facto ban on a range of direct-to-consumer gene reports. What’s followed has been a quick expansion of gene tests that range from reasonable to downright silly.

    Aside from Helix, many others are selling DNA tests, too. One, being advertised on TV, is “Soccer Genomics,” which promises a “personalized report that will help guide player development.” And for $99, a company called Orig3n will sell you a test that claims to predict your kid’s ability to learn languages. Last month, that company had to cancel a planned giveaway of DNA tests at a Baltimore Ravens game, after objections from state regulators.

    Mais ils ne sont responsables de rien... un peu comme les plateformes et les fake-news... ce sont ceux qui y croient qui ont tort. Ben voyons.

    In response to critics, Helix cofounder Justin Kao cautions against a “paternalistic” attitude toward what kind of information consumers should be able to spend their money on. “People should be able to choose how they want to interact and experience DNA-powered insights and decide for themselves what is of value to them,” he says.

  • The rise and fall and rise again of 23andMe : Nature News & Comment
    http://www.nature.com/news/the-rise-and-fall-and-rise-again-of-23andme-1.22801

    23andme has always been the most visible face of direct-to-consumer genetic testing, and it is more formidable now than ever before. In September, the company announced that it had raised US$250 million: more than the total amount of capital raised by the company since its inception. Investors estimate that it is worth more than $1 billion, making it a ’unicorn’ in Silicon Valley parlance — a rare and valuable thing to behold. But for scientists, 23andme’s real worth is in its data. With more than 2 million customers, the company hosts by far the largest collection of gene-linked health data anywhere. It has racked up 80 publications, signed more than 20 partnerships with pharmaceutical firms and started a therapeutics division of its own.

    “They have quietly become the largest genetic study the world has ever known,” says cardiologist Euan Ashley at Stanford University, California.

    Scientists, meanwhile, were dubious. Family history was and is still a more powerful indicator than genes are for predicting the risk of most diseases. “The evidence is increasingly strong that the benefits of direct-to-consumer testing for these kinds of indications are somewhere between small and zero,” says Stanford University lawyer and ethicist Hank Greely, a long-time critic of the company.

Mais pour la revue du MIT, l’originalité d’Helix tient à ce qu’elle appelle un App store pour l’ADN. En effet, explique l’article, les compagnies de génomique classique fonctionnent en une seule étape. On envoie sa salive, puis on reçoit les résultats une bonne fois pour toutes. Helix se veut une plateforme ouverte à des développeurs externes qui fabriqueront des applications susceptibles de donner certaines informations précises sur le contenu de notre génome. Par exemple, la société Exploragen se propose d’analyser les rythmes de sommeil. Insitome de son côté va découvrir la proportion de gènes néandertaliens au sein d’un ADN…

    Évidemment, comme tout ce qui touche à ce domaine très controversé, des questions d’éthique et de risque se posent (comme le fait de devoir payer un loyer à vie pour pouvoir accéder à notre propre code génétique et bénéficier des avancées de la médecine, comme s’en inquiète le professeur de marketing, Christophe Benavent sur son blog). Lorsque tous les résultats sont concentrés au sein d’une même société, on peut à la limite tenter d’avoir un peu de contrôle.

  • Gene Editing for ‘Designer Babies’? Highly Unlikely, Scientists Say - The New York Times
    https://www.nytimes.com/2017/08/04/science/gene-editing-embryos-designer-babies.html

    Here is what science is highly unlikely to be able to do: genetically predestine a child’s Ivy League acceptance letter, front-load a kid with Stephen Colbert’s one-liners, or bake Beyonce’s vocal range into a baby.

    That’s because none of those talents arise from a single gene mutation, or even from an easily identifiable number of genes. Most human traits are nowhere near that simple.

    “Right now, we know nothing about genetic enhancement,” said Hank Greely, director of the Center for Law and the Biosciences at Stanford. “We’re never going to be able to say, honestly, ‘This embryo looks like a 1550 on the two-part SAT.’”

    Even with an apparently straightforward physical characteristic like height, genetic manipulation would be a tall order. Some scientists estimate height is influenced by as many as 93,000 genetic variations. A recent study identified 697 of them.

    Talents and traits aren’t the only thing that are genetically complex. So are most physical diseases and psychiatric disorders. The genetic message is not carried in a 140-character tweet — it resembles a shelf full of books with chapters, subsections and footnotes.

    So embryonic editing is unlikely to prevent most medical problems.

    But about 10,000 medical conditions are linked to specific mutations, including Huntington’s disease, cancers caused by BRCA genes, Tay-Sachs disease, cystic fibrosis, sickle cell anemia, and some cases of early-onset Alzheimer’s. Repairing the responsible mutations in theory could eradicate these diseases from the so-called germline, the genetic material passed from one generation to the next. No future family members would inherit them.

    But testing editing approaches on each mutation will require scientists to find the right genetic signpost, often an RNA molecule, to guide the gene-snipping tool.

  • Biopunk : Subverting Biopolitics – The New Inquiry
    https://thenewinquiry.com/biopunk-subverting-biopolitics

    My own work has also taken a political and critical approach to working with biotechnology. With Stranger Visions, in 2012, I created portraits of strangers from their abandoned DNA. I began by collecting genetic artifacts I found in public: hair, cigarette butts, chewed-up gum. I learned how to extract DNA, how to sequence it, and how to analyze it to generate a portrait of what someone might look like based on an interpretation of their DNA, utilizing scientific research ranging from the established to the speculative. I 3-D printed the portraits life size, in full color, and exhibited these alongside documentation of the artifact, where and when it was collected, and what I analyzed.
    Stranger Visions (installation view)

    The work was meant to call attention to the vulnerability of the body to new forms of surveillance and to predict the future direction of forensic DNA phenotyping—the profiling of a person’s outward characteristics from their DNA. At the time there were clear signals this research was happening, but it hadn’t been publicly discussed.

    Two years later the prediction came true with the launch of Parabon Nanolabs DNA “Snapshot”, offering genomic mugshots to police around the country. The danger of offering stereotypes based primarily on sex and ancestry predictions is that a black box algorithm in the hands of the police can become a new form of racial profiling which appears to have the authority of real genetic evidence.

    Most recently, I worked with Chelsea Manning. Subject to a strict policy of visitation and representation, Chelsea’s image had been suppressed since her sentencing and gender transition in 2013. She realized that DNA could give her a kind of visibility or presence that she had been stripped of for years. Chelsea didn’t want to appear too masculine in the portraits. I realized it was a perfect opportunity to highlight the reductionism of DNA phenotyping. Instead of producing one portrait to represent her, I generated two: one that was algorithmically gender “neutral” and one parameterized “female.” I presented the two portraits side by side to focus attention on the limitations of this technique even in regards to a genetic trait considered “legible.”

    Just as the libertarian fraction of the cyberpunks fantasizes about the singularity putting the mind into software, biopunk-driven positivism fantasizes about DNA code being the instructions for life itself. “We have discovered the secret of life.” This was how Watson and Crick bragged about their discovery of the DNA double helix after poaching the work of their colleague Rosalind Franklin. Code is the ultimate dream.

  • Boom in human gene editing as 20 CRISPR trials gear up | New Scientist
    https://www.newscientist.com/article/2133095-boom-in-human-gene-editing-as-20-crispr-trials-gear-up

    The CRISPR genome editing revolution continues to advance at an astounding pace. As many as 20 human trials will be under way soon, mostly in China, New Scientist has learned.

    One of these trials will involve the first-ever attempt to edit cells while they are inside the body. The aim is to prevent cervical cancers by using CRISPR to target and destroy the genes of the human papillomavirus (HPV) that cause tumour growth. This study is due to begin in July at the First Affiliated Hospital of Sun Yat-Sen University in China.

    Gene therapy, which involves adding extra genes to cells, was first used to cure people in 1990, but it is mainly useful for treating rare genetic disorders. In contrast, gene-editing, which involves altering existing genes inside cells, promises to treat or cure a much wider range of conditions, from HIV infection to high blood cholesterol.

    The HPV trial, meanwhile, will break new ground. Instead of editing cells outside the body, a gel containing DNA coding for the CRISPR machinery will be applied to the cervix. The CRISPR machinery should leave the DNA of normal cells untouched, but in cells infected by HPV, it should destroy the viral genes, preventing them from turning cancerous.

    “Targeting HPVs seems a sensible approach if they can deliver the genome-editing components to sufficient numbers of cells,” says Robin Lovell-Badge of the Crick Institute in the UK.

    #génomique #médecine
    “It is tricky to do these experiments in animals as they are not infectable by HPV,” says Bryan Cullen of Duke University Medical Center in North Carolina, whose group also hopes to use gene editing to get rid of HPV. But there is a risk of off-target mutations leading to cancer, he warns.


  • 23andMe Is Making Its First Foray into At-Home Research, to Study Pain - MIT Technology Review
    https://www.technologyreview.com/s/607928/23andme-is-making-its-first-foray-into-at-home-research-to-study-p

    Une expérience médicale menée at home par les usagers de 23andMe. Une certaine conception de la médecine, dont l’entreprise est familière.

    “It was uncomfortable and slightly painful, but nothing like wearing wet gloves and shoveling snow for an hour at 10 below zero,” says Pardy, who lives in northwest Vermont. Most people can stand to keep their hands in near-freezing water for at least 100 seconds, according to 23andMe.

    The experiment Pardy did is known as a cold pressor test, and it’s one of many used to gauge a person’s tolerance to pain. It’s part of a new study 23andMe announced earlier this month to study the genetic links of pain tolerance, and it represents the company’s first foray into at-home research.

    23andMe has previously launched studies on medical conditions like depression, fertility problems, and irritable bowel disease, using surveys to ask participants about things like their health history, lifestyle, and diet (see “23andMe Pulls Off Massive Crowdsourced Depression Study”). The new study also includes two surveys about pain tolerance and pain history, but this is the first time the company has asked people to do an experiment on their own and report the results.

    Carrie Northover, director of research services for 23andMe, says the goal of the study is to “understand genetic factors associated with experiencing pain and response to medications that help alleviate pain.” Previous research has suggested that multiple genetic factors are at play in chronic pain, and that certain groups of people report pain more often than others.

    Ajay Wasan, vice chair for pain medicine at the University of Pittsburgh Medical Center, says the cold pressor test is only one way to measure pain. There are a range of other tests, including ones that measure a person’s tolerance to heat, pin pricks, and pressure.

    “The problem is no one single experimental pain test maps really well to overall pain sensitivity and doesn’t have high correlation to someone’s clinical chronic pain or their response to treatment,” he says.
