If 23andMe goes bust, what happens to its DNA database? Premium

23andMe is on the brink of bankruptcy. This has raised concerns about what will happen to the troves of genetic data it has in its possession.

Since it was founded nearly two decades ago, 23andMe has grown into one of the largest biotechnology companies in the world. Millions of people have used its simple genetic testing service, which involves ordering a saliva test, spitting into a tube, and sending it back to the company for a detailed DNA analysis.

But now the company is on the brink of bankruptcy. This has raised concerns about what will happen to the troves of genetic data it has in its possession.

The company’s chief executive, Anne Wojcicki, has said she is committed to customer privacy and will “maintain our current privacy policy”.

But what can customers of 23andMe themselves do to make sure their highly personal genetic data is protected? And should we be concerned about other companies that also collect our DNA?

23andMe is one of the largest companies in the crowded marketplace for direct-to-consumer genetic testing. It was founded in 2006 in California, launching its spit test and Personal Genome Service the following year, at an initial cost of US$999. This test won Time magazine’s Invention of the Year in 2008.

Customers eagerly took up the opportunity to order a saliva collection kit online, spit in the tube and mail it back. In a few weeks when the results were ready they could find out about their health, ancestry, and other things like food preferences, fear of public speaking and cheek dimples.

The price of testing kits dropped rapidly (it’s now US$79). The company expanded globally and by 2015 had 1 million customers. The firm went public in 2021 and initially the stock price soared. As of 2024, the company claims 14 million people have taken a 23andMe DNA test.
