MGI Phenotype FUNCTION: This gene encodes an enzyme that catalyzes the conversion of (S)-2,3 oxidosqualene to lanosterol. The encoded protein is a member of the terpene cyclase/mutase family and catalyzes the first step in the biosynthesis of cholesterol, steroid hormones, and vitamin D. [provided by RefSeq, Feb 2015]
