The once-popular genetic testing company will be acquired by Regeneron after filing for bankruptcy, but the questions about getting personal data out of the company persist.

Biotech giant Regeneron announced Monday that it would acquire DNA testing company 23andMe for $256 million following a bankruptcy auction. The deal includes access to 23andMe's massive personal and genetic data trove from more than 15 million customers.

The DNA testing firm 23andMe says it has entered into an agreement to be acquired by Regeneron Pharmaceuticals for $256m (£192m). It comes two months after the company filed for bankruptcy protection in the US.
