It is best known for providing a direct-to-consumer genetic testing service in which customers provide a saliva sample that is laboratory analysed [1] to generate reports relating to the customer's ancestry and genetic predispositions to health-related topics. The company is named for the 23 pairs of chromosomes in a normal human cell. In23andMe became the first company to begin offering autosomal DNA testing for ancestry, which all other major companies now use. Its saliva -based direct-to-consumer DTC genetic testing business was named "Invention of the Year" by Time magazine in The company was founded by Linda AveyPaul Cusenza and Anne Wojcicki in to provide genetic testing and interpretation to individual consumers.

In June23andMe created a brand marketing advertisement featuring Gru from the movie Despicable Me. On July 25,23andMe announced it is partnering with GlaxoSmithKline and will allow the pharmaceutical company to use the test results from 5 million customers to design new drugs. In January23andMe announced that it would layoff about of its employees.

The new genetic testing service and ability to map significant portions of the genome has raised controversial questions, including whether the results can be interpreted meaningfully and whether they will lead to genetic discrimination. Inthe states of New York and California each provided notice to 23andMe and similar companies, that they needed to obtain a CLIA license in order to sell tests in those states.

In Novemberthe FDA published guidance on how it classified genetic analysis and testing services offered by companies using instruments and chips labelled for "research use only" and instruments and chips that had been approved for clinical use.

Our relationship with the FDA is extremely important to us and we are committed to fully engaging with them to address their concerns. This makes the regulatory process with the FDA important because the work we are doing with the agency will help lay the groundwork for what other companies in this new industry do in the future. On December 5,23andMe announced that it had suspended health-related genetic tests for customers who purchased the test from November 22, in order to comply with the FDA warning letter, while undergoing regulatory review.

In Mayit was reported that 23andMe was exploring alternative locations abroad, including Canada, Australia, and the United Kingdom, in which to offer its full genetic testing service. In23andMe submitted a k application to the FDA to market a carrier test for Bloom syndromewhich included data showing that 23andme's results were consistent and reliable and that the saliva collection kit and instructions were easy enough for people to use without making mistakes that might affect their results, and included citations to the scientific literature showing that the specific tests that 23andMe offered were associated with Blooms.

On October 21,23andMe announced that it would begin marketing carrier tests in the US again. In Aprilthe FDA approved the applications for ten tests: late-onset Alzheimer's diseaseParkinson's diseaseceliac diseasehereditary thrombophiliaalpha-1 antitrypsin deficiencyglucosephosphate dehydrogenase deficiencyearly-onset of dystoniafactor XI deficiencyand Gaucher's disease. In Marchthe FDA approved another de novo application from the company, this one for a DTC test for three specific BRCA mutations that are the most common BRCA mutations in people of Ashkenazi descent ; they are not however the most common BRCA mutations in the general population, and the test is only for three of the approximately 1, known mutations.

These mutations increase the risk of breast and ovarian cancer in women, and the risk of breast and prostate cancer in men. Customers provide a saliva testing sample that is partially single nucleotide polymorphism SNP genotyped and results are posted online. After the sample is received by the lab, the DNA is extracted from the saliva and amplified so that there is enough to be genotyped.

The DNA is then cut into small pieces, and applied to a glass microarray chipwhich has many microscopic beads applied to its surface. Each bead has a probe on it that matches the DNA of one of the many variants the company test for. If the sample has a match in the microarray, the sequences will hybridizeor bind together, letting researchers know that this variant is present in the customer's genome by a fluorescent label located on the probes.I've been interested in what 23andMe is doing ever since I heard they were planning to develop drugs based on genetic information.

The test came with instructions, a tube for me to spit in and a special sealed bag to enclose the tube in when I was done. Spit is one of the most noninvasive ways to collect DNA. Spitting into a tube wasn't as easy as I expected. My apologies to my coworkers who had to hear me do this for about five minutes. That way, they have enough to run it a second time.

It was time to seal it up and send it on its way. Before I shipped it in, I had to register my test online. I also got to decide if I wanted to have my genes used to research and develop treatments for diseases.

The kit came as its own return shipping. All I had to do was pop it in my nearest mailbox and it was on its way! The box is conveniently labeled "exempt human specimen," which is a creepy-sounding way of letting shippers know my package doesn't contain anything infectious.

After seven weeks, my results arrived via email. In total, I had 62 reports waiting for me based on my 23 pairs of chromosomes from mom and dad. The reports covered everything from family history to physical traits and genetic variants related to diseases that I could pass down to my kids. Of course, I had to look at my ancestry breakdown.

To no one's surprise, I am very Northwest European. Drabant Conley said this information comes from over 30 reference populations, or the genetics of people who have lived in a geographic area for multiple generations, and from other 23andMe users whose grandparents all came from the same place. My DNA is then compared to those populations to see if there are matching bits. The new test could also tell me more about my health and wellness.

But, Drabant Conley said, this result is not intended to be used as a diagnostic test — had I been a good sprinter I'm notthis would just reinforce why I'm so good. So I wasn't surprised to see this test's "limitations" laid out clearly.Now is the time to find out what else you can learn about from your genetic raw data file.

Ancestry has tested over 15 million people, while 23andMe has tested over 10 million. It has a massive database of 15 million customers who are potential DNA matches. This makes AncestryDNA incredibly useful for genealogical research purposes. This is a breakdown of what regions of the world your ancestors came from based on how your DNA compares to millions of other DNA samples referred to as reference populations.

By seeing how closely your DNA matches specific genetic markers from these areas, the testing companies can give you a guess as to how much of your DNA comes from each region. It is important to keep in mind that these are only estimates, and the more specific you go, the lower the statistical confidence becomes. These estimates are based on the most up to date research and algorithms, but everyday researchers want to learn more. AncestryDNA has a much larger customer database 15 million customers from other people who have been tested, which means their results might be a little more accurate, but probably not enough to make a difference.

This is the DNA passed down to you by all of your ancestors — both maternal and paternal lines. See the Health Screening section below for more details. Probably the single biggest benefit of having genealogical DNA testing done is to connect with your living relatives. Chances are you know your aunts, uncles, and first cousins, but a lot of us have never met our second cousins and may have no clue how many third or fourth cousins we have out there or who they are.

Both 23andMe and AncestryDNA provide you with ways to connect with your cousins and other living relatives. You have to agree to share your results before anyone can find you, or before you can find anyone else. First, neither of these two companies give your info out to everyone, only to people who are a close genetic match.

While both companies offer this service, AncestryDNA is much better when it comes to connecting with family members. Ancestry is all about genealogy, and the people who use it want to know more about their relatives and ancestors.

Anyone who gets tested through AncestryDNA is likely to want to share their results and will welcome hearing from you. On the other hand, many of the people who get tested through 23andMe are doing it because of the medical screening more so than the genealogical aspects.

That means they are much less likely to be interested in sharing their info or even replying to messages. AncestryDNA has tested a lot more people so far, too, 15 million compared to 10 million through 23andMe. Ancestry also lets you connect your DNA to your online family tree, and helps you search possible matches from millions of other trees. The results you see on both websites are summaries of your test and how your results compare to other people.

As we mentioned above, if you test through 23andMe, your options for connecting your results to genealogical research may be limited. That means you can use all of the incredible tools that other companies offer, in addition to your results and tools from 23andMe or AncestryDNA. The site uses raw DNA that customers export from every major testing company on the market today. It gives you the option of getting a health test done based on your DNA. The health screening costs more, but it could be worth it.

When you get a health screening done through 23andMe, you will receive a set of four reports: carrier status reports, trait reports, wellness reports, and genetic health risk reports. You can use 23andMe health screening as a starting point to find out more about your health risks, but you should never rely on them for health advice or guidance.

Always be sure to consult a qualified healthcare provider before making any health-related decisions. Our dominant genes are more obvious because they are the ones that affect our appearance and health. Recessive genes are genes that are not active in you, but which can be passed down to your children. The health screening checks for conditions such as Sickle Cell Anemia, Cystic Fibrosis, Muscular Dystrophy, and about 40 other genetic diseases and disorders.

Our DNA directly affects not only our health but our appearance. You may already have a good idea of what your traits are, but there could be a few surprises. Cheek dimples, freckles, hair curliness, male pattern baldness, and eye color are all controlled by our DNA, along with many other traits.

The Trait Reports from 23andMe can help you predict your future appearance and that of your children.The major reason for the downsizing?

Simply put, consumers aren't buying as many at-home DNA tests as they used to. The first sign came in the summer, when Illuminamaker of the DNA sequencing machines that are used by Ancestry and 23andMe, acknowledged in an earnings call to investors that the category had hit a lull. CEO Francis DeSouza didn't share an explanation for that, but noted that Illumina was taking a "cautious view" of the opportunity in the near term.

Orasuremaker of the spit tubes used by consumer DNA testing companies, has also seen its stock take a hit. At that time, some smaller companies were already feeling the impact.

Helix, a start-up that spun out of Illumina to build an "app store" model for DNA tests, cut staff in May. The company revealed to Bloomberg that it was shifting its focus away from consumers to population health, meaning it would work with health industry partners. A few months later, Veritas Genetics — another company focused on consumers that sold more expensive but more detailed whole genome sequencing tests — shuttered its U.

So what happened? There hasn't yet been a detailed study to understand the shift in consumer thinking around these tests. But CNBC spoke with some of the leading genetics experts and doctors, who shared a few theories. Dawn Barry, a former Illumina executive with a start-up in the space called LunaDNAblames a few factors, especially privacy concerns. Consumers have seen a slew of reports in the past few years about how companies are using their personal data for targeted advertising, without their knowledge, and might be feeling particularly sensitive about their health information.

Companies like 23andMe do make money off this information. Her company does ask for consent from users and it has publicly explained its revenue model, but a big part of its business involves its relationships with pharmaceutical companies like GlaxoSmithKline.

Making matters worse for these companies, suggests Barry, is the Golden State Killer case. Law enforcement honed in on a suspect after running DNA from a decades-old crime scene through a free online database, where anyone can upload their genetic information. A suspect was found through a distant relative who might have paid for a test via Ancestry or 23andMe, and then uploaded it into the database.

The case raised all sorts of complicated questions about whether genetic information is fundamentally different than other types of data because it implicates family members and not just individuals.

Other experts suspect that consumer DNA testing companies might have run out of early adopters. The theory goes that there's about 20 million or 30 million consumers who are naturally interested in learning more about their family background, and it's not that challenging or expensive to sell tests to them.

At this point, many of these people have already been sold to, and there's no reason for them to buy a second test.

Ancestry has sold about 14 million tests, and 23andMe has sold some 9 million. But many people are wary about learning information they might not want to know — like the father who raised them isn't their biological father — or that they have a risk for a genetic disease that they can't take a pill to prevent.

There's likely a larger consumer segment that's interested, but still wary about these tests. They might not believe that the information is valuable enough to warrant the price tag.

A decade or so in, "these companies are beginning to tap out the market. Mittelman notes that customer acquisition costs, including ad dollars these companies need to spend on sites like Facebook, will increase over time. What's noteworthy about the recent round of layoffs is that Ancestry kept all of its employees at its Ancestry Health business. And 23andMe is still highly focused on its drug development business.

That suggests that both companies are indeed hinging their future on developing powerful health applications. Robert Green, a professor of genetics at Harvard Medical School. As Green explains, it's been a challenge for doctors to understand how genetics can inform their patient care.

Many haven't had the education about genetics to understand how to talk about it with their patients or recommend tests that might be beneficial.Watch live. Essential FAQ. Listen: Special podcast episode.

At most, that you carry a DNA variant that, according to research, is associated with a higher risk of a disease. For the rare clotting disorder hereditary thrombophilia, for instance, the report will say that you do or do not carry a variant called Factor V Leiden in the F5 gene and a variant called Prothrombin GA in the F2 gene. Of course, you can also look it up.

The company might soon also offer testing for genetic variants linked to factor XI deficiency excessive bleedingceliac disease, anemia-causing G6PD deficiency, the movement disorder early-onset primary dystonia, and the blood illness hereditary hemochromatosis. Is it worth it? Geneticists have studied more people of European descent than other groups, so they have more data on white people.

Not at all; this is a direct-to-consumer product. Patient empowerment, you own your DNA, and all that. Genes account for most of the risk of developing rare disorders like Factor XI Deficiency three variants in one gene, F11, are linked to excessive bleeding after accidents or surgery.

Yes, and this is what experts most fault 23andMe for. For some diseases, she said, the chance that a disease-linked gene will lead to the disease is greater if the disease runs in the family.

That sort of analysis is what genetic counselors provide. Might genetic variants not picked up by the tests increase or decrease my risk of acquiring these diseases? As with any gene, it depends on whether you have two copies or one. If two copies, your children inherited it.

If one, they have a chance of doing so. This article is reproduced with permission from STAT. It was first published on April 7, Find the original story here.

Health Apr Nation Apr This innovative tool searches the 23andMe database and finds people that share enough DNA to be your relatives. Serious genealogists are using it to learn more about their family trees. I know it works, because I quickly found and confirmed a previously unknown third cousin.

In addition, this test provides a very robust test of close relationships. Traditional DNA kinship testing compares two people on very specific autosomal markers. Their test includes about a million autosomal markers. And the test works equally well for men and women. If two people who suspect a close relationship take the test, Relative Finder will show them whether or not they are related. What's more, it can distinguish degrees of close relationships such as full siblings, half siblings, and first cousins.

Such resolution among close relationships is possible because the amount of shared DNA drops dramatically as the genetic distance increases. The following table show the theoretical amount of shared DNA for some close relationships:. Since DNA combines randomly, actual percentages can vary considerably from the series of perfect splits implied in this table.

But you usually have enough additional information to know that only one of those relationships makes sense. The people you match show up in a table that you can sort in various ways. The image below shows the top records of a real table. This person tested several close relatives. The known relationships are shown here in red. The second column shows how Relative Finder has classified the relationship. The next to the last column shows the percent of DNA you share with each person.

And the far right column shows the number of DNA segments you share. The following three samples show you what to look for when you get your own test results. A Family Inheritance diagram for full siblings will have many large completely identical segments indicated in dark blue.

NOTE: The dark blue segments may appear as black on your monitor. Sisters like the example shown here should show at least half-identity across the full length of the X chromosome. Brother-brother and brother-sister pairs will typically see patches of half-identity on the X.

A Family Inheritance diagram for half siblings would look something like this diagram. Often, the only possibilities are a close relationship or no relationship at all. In those cases graphs like these should clearly indicate what the right answer is. And unlike traditional DNA kinship testing, even brother-sister half siblings should be obvious.

This Family Inheritance diagram compares second cousins. DNA splits and recombines with every generation. So by the time you get this far out on your family tree only a few short segments of matching DNA survive. The projections get fuzzier as the relationship gets weaker.

You can't always tell a first cousin from a second cousin.
