General Discussion

Trichorhinophalangeal syndrome type I (TRPS1) is an extremely rare inherited multisystem disorder. TRPS1 is characterized by thin, sparse scalp hair, unusual facial features, abnormalities of the fingers and/or toes, and multiple abnormalities of the "growing ends" (epiphyses) of the bones (skeletal dysplasia), especially in the hands and feet. Characteristic facial features may include a rounded (bulbous) "pear-shaped" nose, an abnormally small jaw (micrognathia), dental anomalies, and/or unusually large (prominent) ears. In most cases, the fingers and/or toes may be abnormally short (brachydactyly) and curved. In addition, affected individuals may exhibit short stature. The range and severity of symptoms may vary from case to case. In most cases, Trichorhinophalangeal syndrome type I has autosomal dominant inheritance.
