Summaries for Disordered Steroidogenesis Due to Cytochrome P450 Oxidoreductase...

OMIM : 53 This rare variant of congenital adrenal hyperplasia, caused by mutations in the POR gene, results in apparent combined deficiency of P450C17 (609300) and P450C21 (613815) and accumulation of steroid metabolites. The most striking phenotypic feature is that affected girls are born with ambiguous genitalia, indicating intrauterine androgen excess. After birth, however, virilization does not progress and amounts of circulating androgens are low or normal. Affected boys are sometimes born undermasculinized. Boys and girls can present with bone malformations, sometimes suggesting the pattern seen in patients with Antley-Bixler syndrome (see 207410) (summary by Arlt et al., 2004). (613571)

MalaCards based summary : Disordered Steroidogenesis Due to Cytochrome P450 Oxidoreductase Deficiency, also known as disordered steroidogenesis due to cytochrome p450 oxidoreductase, is related to aromatase deficiency and cytochrome p450 oxidoreductase deficiency, and has symptoms including low-set ears, clinodactyly and hypertension. An important gene associated with Disordered Steroidogenesis Due to Cytochrome P450 Oxidoreductase Deficiency is POR (Cytochrome P450 Oxidoreductase). Affiliated tissues include bone, ovary and adrenal gland.

UniProtKB/Swiss-Prot : 71 Disordered steroidogenesis due to cytochrome P450 oxidoreductase deficiency: A disorder resulting in a rare variant of congenital adrenal hyperplasia, with apparent combined P450C17 and P450C21 deficiency and accumulation of steroid metabolites. Affected girls are born with ambiguous genitalia, but their circulating androgens are low and virilization does not progress. Conversely, affected boys are sometimes born undermasculinized. Boys and girls can present with bone malformations, in some cases resembling the pattern seen in patients with Antley-Bixler syndrome.
