23andMe would like to introduce you to your genes. The ACTN3 gene, in the guise of an old coach, effects muscle composition. BTBD9, a woman sleeping in a rotating bed, can impact how you move in your sleep. HLA-DQA1 and HLA-DQB1, two office workers sitting in a command center, may determine whether or not you develop celiac disease. For a limited time 23andMe is offering a discounted price for its testing in honor of Mother's Day.
