Genetic testing company 23andMe's bankruptcy has led to a new consumer privacy issue: what happens to the DNA of millions of Americans when it goes on sale?

Me, a standard-bearer for the at-home health movement, announced on March 23 that it has filed for Chapter 11 bankruptcy to facilitate a sale, prompting many of its 15 million customers to wonder: What happens to my genetic data now?

23andMe, the company whose mail-in self-testing kits became synonymous with DNA testing, is filing for bankruptcy . Anne Wojcicki, who co-founded 23andMe in 2006, is stepping down as CEO as the company tries to find a buyer amid slowing sales four years after going public.
