Question

Please read the article bellow and discuss the shift in the company's approach to genetic analysis. Please also discuss what you think about personal genomic companies' approaches to research. Feel free to compare 23andMe's polices on research with another company's. Did you think the FDA was right in prohibiting 23andMe from providing health information?

These are some sample talking points to get you thinking about the ethics of genetic research in the context of Big Data. You don't have to answer all of these questions and I highly recommend that you bring up other talking points. You could find a more recent paper on 23andMe or look up their more current policies and discuss those.

That responsiveness sets the 23andMe cohort apart from the average subjects recruited into a research study, who are often "ready to quit at the relatively other variants that are likely to be inherited alongside those tested directly.

SPECIAL SECTION MUTATION AND HUMAN DISEASE cism," says Mark Cookson, a cell biologist studying Parkinson's disease at the Na- tional Institute on Aging's laboratory of neurogenetics in Bethesda, Maryland. Ca- sual questionnaires seemed to many to be a poor substitute for a medical exam or a patient's health records. "The clinical guys were saying, Well hang on, if you don't know that someone has Parkinson's, how will you get clean data sets?'" Cookson says that skepticism has faded somewhat. For one thing, the search for sta- tistically significant associations between a trait and a DNA sequence "is a numbers game," he says, and with enough responses, concerns about reliability "melt a little bit." And 23andMe has shown in several studies A cohort of customers More than a million people have had the DNA from their saliva analyzed by 23andMe, most paying $99 for the service, and more than 800,000 have allowed that DNA to be used in research Customer age 140,000 70,000 0 40 10 20 30 50 60 70 80 90 100 Decadal distribution Customer ancestry that the associations its researchers turn up match results from other groups By 2012, 23andMe had 180,000 customers, and had contributed to studies identifying new genetic associations for freckles, curly hair, alopecia, Parkinson's disease, and hypothyroidism. At that year's annual gathering of the American Society of Human Genetics (ASHG), 23andMe's prin- cipal scientist, statistical geneticist David Hinds, noticed that his status had changed. "Between one ASHG meeting and the next, it went from largely disinterest in what we were doing-thinking it was not very relevant-to being approached by lots of people who were interested in collaborat- ing with us, getting access to our data."

A saliva stockpile collaboration with academic labs. The 23andMe team has also demon- strated-retrospectively-that its database can help guide drug discovery. At the 2014 ASHG meeting, they presented an analy- sis of 2751 candidate drugs showing that 23andMe data could predict which ones succeeded in clinical trials. They observed a nearly twofold increase in the odds that a drug would ultimately be approved by FDA if the 23andMe database revealed an asso- 2-liter bottle ciation between the disease trait and a SNP somewhere on or around the gene whose product the drug targeted, compared with a drug without a genetic association 2 mL per sample But association studies alone are feeble drug discovery tools.

standby, the SNP chip, to partial- or full- genome sequencing. SNP chips erally geared toward flagging common mutations-occurring in roughly 3% to 5% of the population-and these have so far failed to explain a large percentage of a person's really done that, so it would be churlish of genetic risk for common diseases. 23andMe's chip has been tweaked to include many SNPS, but it can't physically accommodate hundreds of uncommon variants for every given gene. And it can only probe for known mutations-not reveal new ones. Newer efforts to scan huge collections of DNA for disease-causing mutations- including geneticist J. Craig Venter's San Diego-based Human Longevity, Inc. and the 1-million-person cohort launched in January as part of President Obama's pre cision medicine initiative-are betting on large-scale genome sequencing instead (see sidebar, p. 1475). As DNA sequencing gets cheaper, "a whole realm of genetic variation that we've just not had access to is possible," a DNA region suspected of having a disease connection to a druggable target.

Last December, on the same day the 61-year-old drug discovery veteran announced his re- tirement from a 15-year career at Genentech, he got an email from Wojcicki. "I knew he had not retired," she says. "I grew up on Stanford's campus. I know his phenotype. That man is never going to stop." Wojcicki says she had long been debating whether the company should do its own drug discov- ery, and Scheller's enthusiasm for the idea pushed her over the edge At 23andMe, Scheller is on foreign ground. The informatics experts on Tung's team are not his scientific ilk.

He is checking out po- tential lab space in South San Francisco and talking to contract labs. Slowly, 23andMe may start to look more like a typical biotech firm, doing the dicey work of drug develop- ment: finding candidate genes, screening compounds that might interact with them or their proteins, testing the compounds in animals and then in people. The company has revealed almost noth- ing about what its new group will pursue. The only area definitively ruled out is neuro- psychiatric disease-because of its "particu- lar complexities," says Scheller, who headed a Stanford neuroscience lab before joining Genentech. He also says that 23andMe's first drug candidates will likely be antibodies that target disease-related molecules, be- certain kinds of compromises."

Answer #1

Human genome project started in 1990 and completed in 2003, 13 years project completed by government agencies NIH and private sector Celera Genomics, was great work done in the field of genetics.

As similar to it, 23andMe, has been working in the field of genetics and do a lot of research for human welfare. They provide better treatments and design personalized medicine to us at low cost. Besides that, we can also know our ancestoral history or genetic relationships. This copy provides personalized medicine at very reasonable charges and also give all the genomic data to the patient for future study.

The prohibition taken by the FDA against this company is unjustified, because the strategy and facilities they provide to our society is very precious. And there is no ethical issues related to their work, because it's an independent work and, our own choice to choose their terms and conditions for the treatment.

Other than it, the data collected by them also beneficial for the research and development sector.

The studies, survey and genome data analysis in future help us to solve the mystery behind the curcial disease or genetic disorders, helps to design personalized medicine for better health care at cheaper cost and also to study evolutionary realtionship or to find ancestoral realtionship of human society.

The most important point is that, the succesful growth of 23andMe against all the odds because of the the benefits they provide to their customers.
