Single-gene mutations that lead to atopic dermatitis identified

Researchers have identified mutations in a gene called CARD11 that lead to atopic dermatitis, or eczema, an allergic skin disease. Scientists discovered the mutations in four unrelated families with severe atopic dermatitis and studied the resulting cell-signaling defects that contribute to allergic disease. Their findings also suggest that some of these defects potentially could be corrected by supplementation with the amino acid glutamine.
