The genetic basis of alopecia areata, one of the most common human autoimmune diseases, is largely unknown. This study reports a genome-wide association for this trait that implies the involvement of acquired and innate immunity. Among significant associations are the cytomegalovirus UL16-binding protein genes, which encode activating ligands for the natural killer cell receptor, NKG2D, here implicated for the first time in any autoimmune disease.
