Trichorhinophalangeal syndrome type 2 (TRPS2), also known as Langer-Giedion syndrome, is an extremely rare inherited multisystem disorder.[1] The condition is characterized by intellectual deficit and numerous other abnormalities including excess folds of skin, multiple bony growths (exostoses), characteristic facial features, and cone-shaped phalangeal epiphyses (the growing ends of the bones in the fingers).[2] The range and severity of symptoms varies greatly from person to person.[1] TRPS2 is transmitted in an autosomal dominant manner, but many sporadic cases have been reported.[2] TRPS2 is due to the absence of genetic material (chromosomal deletions) on chromosome 8, which often includes the TRPS1 gene and EXT1 gene. The size of the deletion varies from person to person.[1][3]
