NCIt definition : Human CYP2D6*44 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*44 protein. The CYP2D6*44 allele exhibits a clinically-relevant
SNP (g.2950G C) in the intron 6 donor splice junction that results in a splicing defect.
This alteration abolishes the enzymatic activity of the cytochrome P450 2D6*44 protein.;
