NCI: Human CYP3A5*3 allele is located in the vicinity of 7q21.1 and is approximately 32 kb in length. This allele, a variant form of the human CYP3A5 wild-type allele, encodes cytochrome P450 3A5*3 protein. The CYP3A5*3 allele exhibits a clinically-relevant SNP (g.6986A>G) in intron 3 that results in a splicing defect and premature stop at 102 amino acids. This alteration severely decreases the enzymatic activity of the cytochrome P450 3A5*3 protein.
