23andMe DNA test for Alzheimer's risk approved for sale in US

New Scientist 

Want to know what's in your genes? People in the US will soon be able to buy a genetic test that tells them how likely they are to develop 10 diseases, including late-onset Alzheimer's. The saliva-based test is being marketed by 23andMe, a company based in California. The firm already offers "spit kits" for US-based customers who want to find out about their ancestry or risk of passing on certain genetic diseases to their children. But in 2013, the Food and Drug Administration banned 23andMe from offering a test that assessed a person's genetic risk for 254 disorders and conditions.
