The cholesterol side-chain cleavage enzyme P450scc, encoded by CYP11A1, catalyzes the conversion of cholesterol to pregnenolone in the first step of steroid hormone biosynthesis. CYP11A1 deficiency is commonly associated with adrenal insufficiency, and in 46,XY individuals, with variable degrees of disorder of sex development.
Homozygous mutation of P450 side-chain cleavage enzyme gene (CYP11A1) in 46, XY patient with adrenal insufficiency, complete sex reversal, and agenesis of corpus callosum.
