What is the official name of the CYP4F22 gene?

The official name of this gene is “cytochrome P450, family 4, subfamily F, polypeptide 22.”

CYP4F22 is the gene's official symbol. The CYP4F22 gene is also known by other names, listed below.

What is the normal function of the CYP4F22 gene?

From NCBI 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 gene is part of a cluster of cytochrome P450 genes on chromosome 19 and encodes an enzyme thought to play a role in the 12(R)-lipoxygenase pathway. Mutations in this gene are the cause of ichthyosis lamellar type 3. [provided by RefSeq, Jul 2008]
