Summaries for SC5D Gene

Entrez Gene Summary for SC5D Gene

  • This gene encodes an enzyme of cholesterol biosynthesis. The encoded protein catalyzes the conversion of lathosterol into 7-dehydrocholesterol. Mutations in this gene have been associated with lathosterolosis. Alternatively spliced transcript variants encoding the same protein have been described. [provided by RefSeq, Jul 2008]

GeneCards Summary for SC5D Gene

SC5D (Sterol-C5-Desaturase) is a Protein Coding gene. Diseases associated with SC5D include Lathosterolosis and Mevalonic Aciduria.
