To date, 7 distinct clinical forms of CAH and the corresponding genes are recognized, namely: lipoid adrenal hyperplasia, STAR (OMIM #201710); deficiency of cholesterol side-chain cleavage enzyme, CYP11A1 (OMIM #613743); deficiency of 3β-hydroxysteroid dehydrogenase, HSD3B2 (OMIM #201810); deficiency of 17α-hydroxylase/17,20-lyase, CYP17A1 (OMIM #202110); deficiency of P450 oxidoreductase, POR (OMIM #613571); deficiency of 21-hydroxylase, CYP21A2 (OMIM #201910); and deficiency of 11β-hydroxylase, CYP11B1 (OMIM #202010) (1). Here, HSD3B2 is linked to congenital adrenal hyperplasia.
