Witkop syndrome

A rare autosomal dominant ectodermal dysplasia (OMIM:189500) involving the teeth and nails. Most affected individuals have normal hair, sweat glands and ability to tolerate heat, with variable defects in permanent and primary teeth.
 
Molecular pathology
Defects of MSX1, which encodes a homeobox protein involved in epithelial-mesenchymal signalling that has roles in limb-pattern formation and craniofacial development, cause Witkop syndrome.
