Congenital adrenal hyperplasia consists of a heterogenous group of inherited disorders due to enzymatic defects in the biosynthetic pathway of cortisol and/or aldosterone. This results in glucocorticoid deficiency, mineralocorticoid deficiency, and androgen excess. 95% of CAH cases are due to 21-hydroxylase deficiency.(PDF) Congenital Adrenal Hyperplasia Due to 21-Hydroxylase a387 gr 21 hydroxylaseCongenital adrenal hyperplasia (CAH) is one of the most frequent autosomal recessive diseases.
