Description	An extremely rare inborn error of sterol biosynthesis with manifestations of facial dysmorphism, congenital anomalies (including limb and kidney anomalies), failure to thrive, developmental delay and liver disease. Only 4 cases have been reported in the literature to date. Lathosterolosis is due to mutations in the SC5D gene (11q23.3). A mutation in this gene leads to a deficiency in 3-beta-hydroxysteroid-delta-5-desaturase, which is necessary in the conversion of lathosterol into 7-dehydrocholesterol. This prevents the synthesis of cholesterol, which among other functions acts as a structural lipid, a precursor for bile acids and steroid hormones, and is necessary for the maturation of hedgehog morphogens during embryonic development. Inherited in an autosomal recessive manner.
