DNA-testing companies like 23andMe sell your genetic data to drugmakers and other Silicon Valley startups
Perhaps you didn't intend for that spit sample you shipped off to be used for research on antacids. But that could be what happens with the data that some genetics-testing companies like Ancestry, 23andMe, and Helix have collected from billions of customers and stored in their databases.
Both Ancestry and 23andMe have a history of sharing anonymized consumer data with private companies, also known as "third parties." Last week, 23andMe took that policy to a new level when it announced a plan to share the genetic data of millions of consumers with pharmaceutical giant GlaxoSmithKline to help the company develop new drugs.
23andMe also collaborates with handful of other drug companies and with institutions like P&G Beauty, the company behind Pantene shampoo and the antacid Pepto-Bismol.
