Generalized atrophic benign epidermolysis bullosa is a form of junctional epidermolysis bullosa characterized by skin fragility; atrophic alopecia; sparse eyebrows, eyelashes, and axillary and pubic hair; dystrophic fingernails and toenails; and enamel defects in decidual and permanent teeth. Substantial progress was recently made elucidating the genetic defects underlying this disorder. In affected persons, pathogenetic mutations were identified in the genes encoding the beta 3 chain of laminin 5 (LAMB3) or the 180-kd bullous pemphigoid antigen (BPAG2/COL17A1).
