11β-Hydroxylase deficient congenital adrenal hyperplasia (11β-OH CAH) is an uncommon form of congenital adrenal hyperplasia (CAH) resulting from a defect in the gene encoding the enzyme steroid 11β-hydroxylase which mediates the final step of cortisol synthesis in the adrenal. 11β-OH CAH results in hypertension due to excessive mineralocorticoid effects. It also causes excessive androgen production both before and after birth and can virilize a genetically female fetus or a child of either sex.
