Study zeroes in on mutation linked to zits
NEK9 mutations cause normal hair follicles to develop blackheads and acne cysts.

Little is known about the genetic causes of pimples and other forms of acne that plague most teenagers. In a new study, a team of Yale researchers identified a genetic mutation responsible for the defects that give rise to mild and severe acne. Their finding might point to new targets for acne treatment.

In the study, the Yale-led team took blood and tissue samples from three individuals with a rare form of acne known as nevus comedonicus. By sequencing the genomes of the three subjects, the researchers found that mutations within the gene NEK9 causes defects in the . "We know that all acne is dependent upon hair follicles," said senior author Dr. Keith A. Choate, associate professor of dermatology. "We found that in the setting of NEK9 mutation, hair follicles go from producing normal hair to producing giant blackheads and cysts."

The new understanding provides clues to potentially treating the more common forms of acne. "Before the study, we had no insight that this family of proteins was relevant to acne," Choate said. "It's intriguing to think if we were able to develop a drug that targets NEK9, it might have relevance to treatment of blackheads and ."

The study was published May 5 in the American Journal of Human Genetics.
