Summaries for CYP11A1 Gene

Entrez Gene Summary for CYP11A1 Gene

  • 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 mitochondrial inner membrane and catalyzes the conversion of cholesterol to pregnenolone, the first and rate-limiting step in the synthesis of the steroid hormones. Two transcript variants encoding different isoforms have been found for this gene. The cellular location of the smaller isoform is unclear since it lacks the mitochondrial-targeting transit peptide.

GeneCards Summary for CYP11A1 Gene

CYP11A1 (Cytochrome P450, Family 11, Subfamily A, Polypeptide 1) is a Protein Coding gene. Diseases associated with CYP11A1 include adrenal insufficiency, congenital, with 46xy sex reversal, partial or complete and 46,xy disorder of sex development - adrenal insufficiency due to cyp11a1 deficiency. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include electron carrier activity and heme binding. An important paralog of this gene is CYP24A1.

  • Adrenal insufficiency, congenital, with 46,XY sex reversal (AICSR) [MIM:613743]: A rare disorder that can present as acute adrenal insufficiency in infancy or childhood. ACTH and plasma renin activity are elevated and adrenal steroids are inappropriately low or absent; the 46,XY patients have female external genitalia, sometimes with clitoromegaly. The phenotypic spectrum ranges from prematurity, complete underandrogenization, and severe early-onset adrenal failure to term birth with clitoromegaly and later-onset adrenal failure. Patients with congenital adrenal insufficiency do not manifest the massive adrenal enlargement typical of congenital lipoid adrenal hyperplasia. {ECO:0000269 PubMed:11502818, ECO:0000269 PubMed:12161514, ECO:0000269 PubMed:16705068, ECO:0000269 PubMed:18182448, ECO:0000269 PubMed:19116240}.
