A new study found that seven gene regions associated with the chronic skin condition, rosacea, also play a role in skin pigmentation, immune response, and inflammation. The findings give new insight into the underlying biology of the disease and may hold clues for identifying drug targets used to treat it, according to the researchers at GlaxoSmithKline who collaborated with 23andMe to conduct the study.

A new study by researchers from Stanford Medical School and 23andMe is the first to identify genetic variants associated with rosacea, a chronic skin disease estimated to affect more than...
