Sterol-4-alpha-carboxylate 3-dehydrogenase, decarboxylating is an enzyme that in humans is encoded by the NSDHL gene.[1][2] This enzyme is localized in the endoplasmic reticulum and is involved in cholesterol biosynthesis.[3]

Clinical significance[edit]

Mutations in the NSDHL gene are associated with CHILD syndrome which is a X-linked dominant disorder of lipid metabolism with disturbed cholesterol biosynthesis, and typically lethal in males.[3][4]
