NCIt definition : Human CYP3A5*8 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*8 protein. The CYP3A5*8 allele exhibits a clinically-relevant
SNP (g.3699C T) in exon 2 that results in a R28C coding change. This alteration in
protein sequence decreases the enzymatic activity of the cytochrome P450 3A5*8 protein.;
