As quickly because the genetic checking out corporate 23andMe filed for chapter on March 23, 2025, considerations about what would occur to the private data contained in its large genetic and well being data database have been swift and fashionable. A couple of days after, a U.S. pass judgement on dominated that the corporate may promote its user information as a part of the chapter.
The legal professionals normal of a number of states warned their electorate to delete their genetic information. California advised its electorate to request that 23andMe delete their information and break their spit samples. Michigan’s lawyer normal launched a remark caution that “23andMe collects and stores some of the most sensitive personal information, our genetic code.”
When consumers in the beginning signed up for 23andMe, they agreed to phrases and stipulations and a privateness understand that permits the corporate to make use of their data for analysis and construction in addition to percentage their information, in combination, with 3rd events. If shoppers consented to further analysis, which the overwhelming majority did, the corporate can moreover percentage their particular person data with 3rd events. 23andMe has additionally been transparent that whether it is inquisitive about a chapter or sale of belongings, user data could be bought or transferred.
Whilst 23andMe has warned consumers all alongside about the entirety this is these days going down, many are nonetheless shocked and anxious.
I’m a legal professional and bioethicist who has been learning direct-to-consumer genetic checking out for just about a decade. Figuring out what data 23andMe has been amassing, and the way it could be used if bought or shared, can assist explain considerations for shoppers.
What’s 23andMe?
In 2007, 23andMe, named after the 23 pairs of chromosomes present in a human cellular, used to be some of the first direct-to-consumer genetic checking out corporations to open in the US. It used to be subsidized by way of a big funding by way of Google, which briefly attracted the hobby of alternative traders, permitting 23andMe to thrive when many different direct-to-consumer genetic corporations went briefly into bankruptcy.
The direct-to-consumer trade style is quite easy: A shopper orders a genetic check equipment on-line, spits right into a tube that comes within the mail, returns it to the corporate and accesses their leads to an internet portal. Over 15 million shoppers purchased 23andMe, and the overwhelming majority consented to its analysis. At its top, the corporate used to be valued at US$6 billion.
The destiny of the trove of private data 23andMe has accumulated over time has wide-ranging implications for shoppers.
Whilst the marketplace to start with believed within the worth of 23andMe’s trade style, its inventory has been in decline for years, and the corporate owes loads of thousands and thousands of greenbacks to collectors.
Causes for this speedy decline come with a lower within the sale of check kits after a 2023 hack of just about 7 million other folks’s information, in addition to a failure to benefit sufficient from offering information get entry to to different non-public sector corporations. Loss of non-public hobby in 23andMe information is also associated with the truth that a lot of the tips the corporate collects is self-reported, which is regularly regarded as much less dependable than data written down by way of a health care provider in a scientific file.
What sort of information does 23andMe accumulate?
Whilst the pronouncing is going “If you’re not paying, you’re the product,” 23andMe controlled to persuade its shoppers to each pay for AND be the product. It did this by way of promoting genetic checking out kits to shoppers in addition to amassing an enormous quantity in their treasured information.
And 23andMe gathered extra than simply genetic information generated from shoppers’ spit. 80-five % of shoppers consented to 23andMe analysis, permitting their individual-level information for use for research. The corporate then gathered data from survey questions on their non-public well being and past, equivalent to ingesting conduct and chance tolerance.
Because of this no longer most effective does 23andMe possess the genetic information of 15 million other folks, but it surely additionally possesses virtually one billion further information issues related to this genetic data. This makes the 23andMe dataset doubtlessly very non-public – and really treasured.
In the beginning, drug corporations appeared to agree. As an example, in 2018, 23andMe granted pharmaceutical corporate GlaxoSmithKline an unique license to make use of consented buyer information to expand new medication. GlaxoSmithKline additionally made a $300 million fairness funding in 23andMe. When 23andMe went public in 2021, its $6 billion valuation mirrored the promise of this trade style.
However for over a decade, students, together with me, were caution that permitting 23andMe to assemble and use non-public information used to be no longer one that buyers absolutely understood, or have been in reality pleased with.
What must 23andMe consumers fear about?
In line with present public worry about information privateness, 23andMe has said that there can be no adjustments to the way it shops and protects information throughout its chapter complaints. However as soon as that level is thru, what precisely must consumers fear about?
First, legislation enforcement may use genetic data in civil or felony instances. This came about in 2018, when police used the genetic checking out corporate GEDmatch to assist establish the Golden State Killer. Police pretended they have been consumers searching for family tree information and despatched in an outdated crime scene blood spot. This allowed them to hook up with recognized suspects with blood family who had given their genetic data to the corporate as shoppers. Whilst this used to be in violation of GEDmatch’s personal insurance policies, the proof used to be effectively utilized in court docket.
2d, genetic data might be used to discriminate towards consumers if it displays that they have got or are at prime chance of creating a genetic illness or dysfunction. The federal Genetic Knowledge Nondiscrimination Act prohibits well being insurers and employers from asking about genetic data or the use of it to discriminate in paintings or medical health insurance choices. It does no longer, alternatively, offer protection to towards discrimination in long-term care or lifestyles insurance coverage.
Giving any individual your genetic, scientific and private data provides them alternatives to take advantage of you.

Lots of the warnings from the media and legal professionals normal are thinking about genetic data as a result of it’s distinctive to just one particular person. However direct-to-consumer genetic checking out corporations additionally retain an enormous quantity of private data from the surveys shoppers are requested to finish. A lot of this knowledge might be embarrassing if it have been inadvertently or deliberately printed, equivalent to an individual’s intelligence.
Within the 2025 ebook “Careless People,” former Meta government Sarah Wynn-Williams reported that Fb would use indications of self-consciousness about non-public look, equivalent to deleting a selfie, to advertise attractiveness merchandise. If corporations know such intimate information about an individual, they may no longer most effective be used to promote merchandise, but additionally doubtlessly manipulate them over social media or the web in tactics they don’t even notice. It might be used for centered promoting or to construct algorithms that exploit an individual’s vulnerabilities.
I consider shoppers are proper to be nervous about how their genetic information might be misused. However the survey information containing all types of different non-public data are a minimum of as a lot, if no longer extra, of a privateness drawback. That is specifically regarding if the information is pooled along side different data to be had on the net, like a relationship profile, to create a extra detailed – and private – image of a person.
I’m deleting my very own 23andMe information. At some point, I’d additionally warn shoppers towards freely gifting the personal sector with details about their fears, hopes, barriers and successes.
That data is effective to extra other folks than simply you.
