Research Resource: Correlating Human Cytochrome P450 21A2 Crystal Structure and Phenotypes of Mutations in Congenital Adrenal Hyperplasia.

ABSTRACT: Cytochrome P450 21A2 is a key player in steroid 21-hydroxylation and converts progesterone to 11-deoxycorticosterone and 17α-hydroxy progesterone to 11-deoxycortisol. More than 100 mutations in P450 21A2 have been established in patients thus far; these account for the vast majority of occurrences of congenital adrenal hyperplasia (CAH), which is among the most common heritable metabolic diseases in humans. CAH phenotypes range from the most severe, salt-wasting (SW), to the simple virilizing (SV), and nonclassical (NC) CAH forms. We recently determined the crystal structure of human P450 21A2 in complex with progesterone. To gain more insight into the structural and stability changes underlying the phenotypes of individual mutations, we analyzed 24 SW, SV, and NC mutants in the context of
