Trichorhinophalangeal syndrome type 3
Type of disease: Rare conditions
Trichorhinophalangeal syndrome type 3 (TRPS3), also known as Sugio-Kajii syndrome, is an extremely rare inherited multisystem disorder. TRPS3 is characterized by short stature, sparse hair, a bulbous nasal tip and cone-shaped epiphyses (the growing ends of bones), as well as severe generalized shortening of all finger and toe bones (brachydactyly). The range and severity of symptoms may vary from case to case. TRPS3 is caused by mutations in the TRPS1 gene which is localized to 8q24.12. TRPS3 is inherited in an autosomal dominant manner.
