Rapp-Hodgkin syndrome, an extremely rare inherited multisystem disorder that is apparent at birth (congenital) or during infancy, belongs to a group of diseases known as ectodermal dysplasias. Ectodermal dysplasias typically affect the skin, teeth, hair, and/or nails. Rapp-Hodgkin syndrome is characterized by a reduced ability to sweat (hypohidrosis); an incomplete closure of the roof of the mouth (cleft palate) and/or an abnormal groove in the upper lip (cleft lip); partial or complete absence (hypodontia or partial anodontia) and/or abnormal smallness (microdontia) of primary and secondary (permanent) teeth. Infants and children with the disorder also have abnormally sparse, coarse, wiry scalp hair that is often lost prematurely during adulthood (alopecia); unusually slow-growing, improperly developed nails (dysplastic); and, in some cases, additional physical abnormalities. In most cases, Rapp-Hodgkin syndrome is inherited as an autosomal dominant trait.
