Molecular aspects of hypohidrotic ectodermal dysplasia

Hypohidrotic (anhidrotic) ectodermal dysplasia (HED) is a congenital syndrome characterized by sparse hair, oligodontia, and reduced sweating. It is caused by mutations in any of the three Eda pathway genes: ectodysplasin (Eda), Edar, and Edaradd which encode a ligand, a receptor, and an intracellular signal mediator of a single linear pathway, respectively. In rare cases, HED is associated with immune deficiency caused by mutations in further...
