We’ve all seen the Ancestry.com ads for DNA tests that reveal your ethnic mix. Harmless enough. But what if a similar test indicated you had a low risk for coronary heart disease? Would you start swallowing these 2,000+ calorie bombs at every meal? Not harmless. Consumers are increasingly embracing genetic health risk (GHR) testing to understand their individual risk for developing diseases and the FDA recently released an update to streamline the development and review pathway for GHR tests. These tests can be valuable for drug development (see how Novartis is using genetic testing in an Alzheimer’s trial) and treatment decisions and the CDC has some thoughts on the topic.
