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?

Bankrupt genetic testing firm 23andMe Holding Co. won permission from a judge to try to sell information about customers’ medical and ancestry-related data, a trove that is considered the most valuable asset in the insolvency case — and has become a source of privacy and safety concerns amid the company’s collapse.

Me has filed for bankruptcy, prompting people who've used the service and sent in DNA samples to be analyzed to wonder what will happen to their genetic data.
