CYP3A4 gene allele [Genotype] in Blood or Tissue by Molecular genetics method Nominal
Active
Term Description
The patient's CYP3A4 gene allelic genotype (e.g. *1/*22) based on analysis of multiple variants within the CYP3A4 gene, including c.-392A>G (*1B, rs2740574) and the intron 6 C>T polymorphism (rs35599367, *22).

Part Description
LP417570-1 CYP3A4 gene allele
Cytochrome P450 3A4 (abbreviated CYP3A4) is part of a cluster of cytochrome P450 genes on chromosome 7q21.1. Over 30 single nucleotide polymorphisms (SNPs) have been identified in this gene, most of which are not clinically significant. Few have been found to decrease catalytic activity with certain ligands, including testosterone and nifedipine, in comparison to wild-type metabolism. Examples of these alleles and associated SNPs include CYP3A4*6 (an A17776 insertion), CYP3A4*17 (15615T>C) and CYP3A4*22 (15389C>T). A full list of alleles, nucleotide changes and their described enzymatic activity can be found at http://www.cypalleles.ki.se/cyp3a4.htm.
