Шаблон:Short description Шаблон:Cs1 config Шаблон:Infobox gene CYP3A7 is an enzyme belonging to the cytochrome P450 family. It is 503 amino acids in size and shares 87% of its sequence with CYP3A4. It carries out a similar role in fetuses that CYP3A4 serves in adults.[1] The gene location is 7q22.1.[2]

The CYP3A group of enzymes are the most abundantly expressed members of the cytochrome P450 family in liver. They are responsible for the metabolism of more than 50% of all clinical pharmaceuticals.[3]

The CYP3A7 enzyme hydroxylates testosterone and dehydroepiandrosterone 3-sulphate, which is involved in the formation of estriol during pregnancy. The CYP3A7 gene is part of a cluster of related genes on chromosome 7q21.1. Naturally-occurring readthrough transcription occurs between this gene and the downstream CYP3A51P pseudogene.[4]

Notable alleles

The CYP3A7*1C allele is associated with poor outcomes in some cancer patients, possibly because of the effect of the enzyme on some chemotherapy agents.[5]
