If you are one of the more than 16 million people in the United States who suffer from rosacea, than you may have genetics to blame. A new study has identified two genetic variants strongly associated with people who have the incurable skin disorder, and these same two genes, HLA-DRA and BTNL2, are associated with other diseases, including diabetes and celiac disease. As current treatment options for suffers of rosacea are limited, these new findings will hopefully help scientists understand its cause-and-effect. It will be interesting to see if some kind of gene therapy can be applied or if similar dietary triggers for celiac and diabetes also apply to rosacea.
