NCIt definition : Human CYP2D6*41 allele is located in the vicinity of 22q13.1 and is approximately
4 kb in length. This allele, a variant form of the CYP2D6 wild-type allele, encodes
cytochrome P450 2D6*41 protein. The CYP2D6*41 allele exhibits clinically-relevant
SNPs (g.2850C T; g.4180G C) in exons 6 and 9 that result in R296C and S486T coding
changes. These alterations in protein sequence decrease the enzymatic activity of
the cytochrome P450 2D6*41 protein.;
