NCIt definition : Human CYP2D6*35X2 allele is located in the vicinity of 22q13.1 and is approximately
4 kb in length. This allele, an amplification variant form of the CYP2D6 wild-type
allele, encodes cytochrome P450 2D6*35 protein. The CYP2D6*35 allele exhibits four
SNPs (g.31G A; g.1661G C; g.2850C T; g.4180G C) that result in three coding changes
(V11M; R296C; S486T). The CYP2D6*35X2 allele has two copies of the CYP2D6*35 allelic
variant. This duplication increases the enzymatic activity of the cytochrome P450
2D6*35 protein in subjects who carry this allele.;
