Sterol-4-alpha-carboxylate 3-dehydrogenase, decarboxylating is an enzyme that in humans is encoded by the NSDHL gene.^[5][6] This enzyme is localized in the endoplasmic reticulum and is involved in cholesterol biosynthesis.^[7]

Clinical significance

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.^[7][8]
