Dermatophagia is what’s known as a body-focused repetitive behavior (BFRB). People with this condition gnaw at and eat their skin, leaving it bloody, damaged, and scarred. It’s a condition that’s been around for a long time. In fact, it was first described in the 19th century. But it’s only recently that scientists have been able to pinpoint the exact cause of the condition.
And now, a team of researchers from the University of California, San Francisco (UCSF) has found that it may be linked to a genetic mutation that affects the way the body’s immune system responds to bacteria and viruses.
The findings, published in Nature Communications, could lead to new treatments for people who suffer from this type of skin-eating behavior, as well as new ways to prevent and treat it.
“This is the first study to show that BFRBs are caused by a mutation in a gene that regulates the immune response to pathogens,” said study co-author and UCSF professor of dermatology and pediatrics, Dr. Daniela Rus, PhD.
