<n0:ComplexDefinition xmlns:n0="http://ncicb.nci.nih.gov/xml/owl/EVS/ComplexProperties.xsd#"><n0:def-definition>Human CYP3A4*17 allele is located in the vicinity of 7q21.1 and is approximately 27 kb in length. This allele, a variant form of the CYP3A4 wild-type allele, encodes cytochrome P450 3A4*17 protein. The CYP3A4*17 allele exhibits a clinically-relevant SNP (g.15615T>C) in exon 7 that results in a F189S coding change. This alteration in protein sequence severely decreases the enzymatic activity of the cytochrome P450 3A4*17 protein.</n0:def-definition><n0:def-source>NCI</n0:def-source></n0:ComplexDefinition>
