Gene: [08q2411/EXT1] exostosin 1; exostoses (multiple) 1; trichorhinophalangeal syndrome, type II (Langer-Giedion syndrome; MIM:150230); [TRPS2 ]

CAG	[1] There are 3 forms of multiple exostoses: EXT1, EXT2 (GEM:11p1/EXT2), and EXT3 (GEM:19p1/EXT3). [2] Ludecke-1995 and Hou-1995 showed that the Langer-Giedion syndrome is a true contiguous gene syndrome due to loss of functional copies of both the TRPS1 (GEM:08q2411/TRPS1) and the EXT1 gene and that the EXT1 gene is distal to the TRPS1 gene."
FUN	Hecht-1995 and Raskind-1995 suggested that EXT1 and EXT2 genes have tumor-suppressor function."
