23andMe and the U.S. Food and Drug Administration (FDA) announced last week that the agency allowed marketing of 23andMe's Personal Genome Service Genetic Health Risk (GHR) tests for 10 diseases or conditions. "These are the first direct-to-consumer (DTC) tests authorized by the FDA that provide information on an individual's genetic predisposition to certain medical diseases or conditions, which may help to make decisions about lifestyle choices or to inform discussions with a health care professional," said the FDA in its statement. In 2013, the FDA issued a warning letter to 23andMe requiring that it stop marketing its DTC Personal Genome Service. The FDA had concluded that the $99 saliva test was a class III medical device requiring FDA approval. But a little less than two years later, the company won FDA approval for a DTC genetic carrier test for Bloom Syndrome.
