The human cytochrome P450 CYP3 locus: assignment to chromosome 7q22-qter

Abstract
The cytochrome P-450s are a large multigene family of enzymes involved in the metabolism and detoxification of drugs and chemicals. Using a full length cDNA clone for the human nifedipine oxidase gene (CYP3) and a panel of human-rodent somatic cell hybrids, we have assigned this gene family to chromosome 7q22-qter. A search for RFLPs using this probe yielded no results.
