Gene: CYP21A2

Alternate names for this Gene: CA21H|CAH1|CPS1|CYP21|CYP21B|P450c21B

Gene Summary: This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum and hydroxylates steroids at the 21 position. Its activity is required for the synthesis of steroid hormones including cortisol and aldosterone. Mutations in this gene cause congenital adrenal hyperplasia. A related pseudogene is located near this gene; gene conversion events involving the functional gene and the pseudogene are thought to account for many cases of steroid 21-hydroxylase deficiency. Two transcript variants encoding different isoforms have been found for this gene.

Gene is located in Chromosome: 6

Location in Chromosome : 6p21.33

Description of this Gene: cytochrome P450 family 21 subfamily A member 2

Type of Gene: protein-coding

Gene: DXO

Alternate names for this Gene: DOM3L|DOM3Z|NG6|RAI1

Gene Summary: This gene localizes to the major histocompatibility complex (MHC) class III region on chromosome 6. The function of its protein product is unknown, but its ubiquitous expression and conservation in both simple and complex eukaryotes suggests that this may be a housekeeping gene.

Alternate names for this Gene: D6S60|D6S60E|G11|HLA-RP1|RP1

Gene Summary: This gene encodes a serine/threonine kinase which localizes predominantly to the nucleus. Its specific function is unknown; it is possible that phosphorylation of this protein is involved in transcriptional regulation. This gene localizes to the major histocompatibility complex (MHC) class III region on chromosome 6 and expresses two transcript variants.
