After taking a simple saliva sample, the company analyzes DNA to provide customers with personalized genetic information on ancestry, the risk of getting specific diseases and likely response to drugs.

Last week, 23andMe released a list of what it identified as top genetic findings last year. Among other findings, the company highlighted research recognizing that body shape, or body fat distribution, is influenced by genetics.
