Hypohidrotic ectodermal dysplasia (HED) is a condition characterized by major involvement of ectodermal structures with perturbed formation and maturation of teeth, hair, and sweat glands. HED is caused by defective epithelial-mesenchymal interaction that involves the Ectodysplasin/Edar/Edaradd signaling pathway. Congenital anhidrotic ectodermal dysplasia is a sex-linked disorder characterized by incomplete development of the dermis, resulting in the absence of hair follicles and sweat glands with anodontia in affected males.
