Tricho-rhino-phalangeal syndrome is a rare genetic condition affecting the hair (tricho), nose (rhino), and fingers (phalangeal). The term is often abbreviated to TRPS. There are two main types: Type 1 (or TRPS1) and Type 2 (or TRPS2, sometimes also called Langer-Giedion syndrome, named after the two radiologists who described the first patients). Both conditions cause slow growth with a short stature as an adult, sparse and slow-growing hair, an unusually formed nose of which the tip is more prominent than usual, and short fingers and toes. Type 3 is a term used by some people to describe a more severe form of TRPS Type 1.
