Identification of first genetic mutations linked to atopic dermatitis in African-American children

Two specific genetic variations in people of African descent are responsible for persistent atopic dermatitis (AD), an itchy, inflammatory form of the skin disorder eczema. A new report by researchers in the Perelman School of Medicine at the University of Pennsylvania found that loss-of-function mutations to Filaggrin-2 (FLG2), a gene that creates a protein responsible for retaining moisture and protecting the skin from environmental irritants, were associated with atopic dermatitis in African American children. The study, the first report to deduce the mechanism responsible for the persistent form of the condition in African American children, was published in the Journal…
