Genes affected

FDFT1 (HGNC:3629): (farnesyl-diphosphate farnesyltransferase 1) This gene encodes a membrane-associated enzyme located at a branch point in the mevalonate pathway. The encoded protein is the first specific enzyme in cholesterol biosynthesis, catalyzing the dimerization of two molecules of farnesyl diphosphate in a two-step reaction to form squalene.
