CYP21A2 (Steroid 21-hydroxylase) variants and mutations
CYP21A2 (also known as Steroid 21-hydroxylase) is a human protein-coding gene encoding a steroid 21-hydroxylase protein. It enables cortisol and aldosterone synthesis by 21-hydroxylating adrenal steroid precursors. Biallelic loss-of-function variants cause congenital adrenal hyperplasia, with cortisol deficiency, androgen excess, and in severe forms life-threatening salt wasting. This analysis covers 1,209 CYP21A2 variants and mutations. Of these, 71% have computational variant effect predictions. Disease context includes classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency, congenital adrenal hyperplasia, and hereditary disease. Example CYP21A2 variants include M1V, L2P, and L2Q.
