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

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 95699DefinitionCongenital adrenal hyperplasia due to cytochrome P450 oxidoreductase deficiency is a unique form of congenital adrenal hyperplasia (CAH; see this term) characterized by glucocorticoid deficiency, severe sexual ambiguity in both sexes and skeletal (especially craniofacial) malformations.EpidemiologyIt has an annual incidence of 1/100,000-200,000 live births.Clinical descriptionPrenatal androgen excess is responsible for severe virilization of external genitalia in girls and undervirilization in boys manifesting as a micropenis to severe perineoscrotal hypospadias. Craniofacial malformations observed include large domed forehead, flat nose, midface hypoplasia with proptosis and dysplastic ears and other features similar to those seen in Antley-Bixler syndrome (see this term).EtiologyThis form of CAH is caused by a mutation in the POR gene located on chromosome 7 q11.2.Genetic counselingThe disease follows an autosomal recessive pattern of inheritance.Visit the Orphanet disease page for more resources.

MalaCards based summary : Disordered Steroidogenesis Due to Cytochrome P450 Oxidoreductase Deficiency, also known as disordered steroidogenesis due to cytochrome p450 oxidoreductase, is related to cytochrome p450 oxidoreductase deficiency and aromatase deficiency. 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, and related phenotypes are delayed skeletal maturation and delayed puberty

OMIM : 57 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)

KEGG : 37
Cytochrome P450 oxidoreductase (POR) deficiency is an autosomal recessive disorder with a broad phenotypic spectrum including skeletal malformations resembling the Antley-Bixler syndrome phenotype and abnormalities in adrenal steroid biosynthesis resulting in congenital adrenal hyperplasia.

UniProtKB/Swiss-Prot : 74 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.
