EXT1 - exostosin 1

Entrez Gene Name: exostosin 1
Synonyms: AA409028, Exostoses (multiple) 1, EXT, EXT1, LGCR, LGS, TRPS2, TTV

Gene Summary

  • Human (2131): This gene encodes an endoplasmic reticulum-resident type II transmembrane glycosyltransferase involved in the chain elongation step of heparan sulfate biosynthesis. Mutations in this gene cause the type I form of multiple exostoses. [provided by RefSeq]
