Genes affected
CYP2D7 (HGNC:2624): (cytochrome P450 family 2 subfamily D member 7 (gene/pseudogene)) This gene is a member of the cytochrome P450 gene superfamily. 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 a segregating pseudogene, where some individuals may have an allele that encodes a functional enzyme, while other individuals have an allele encoding a protein that is predicted to be non-functional. In this case, the functional allele is thought to be rare. This locus is part of a cluster of cytochrome P450 genes on chromosome 22. [provided by RefSeq, Jan 2017]
