NCIt definition : Human CYP2D6*6 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*6 protein. The CYP2D6*6 allele exhibits a single nucleotide deletion
(g.1707delT) in exon 3 that results in a frameshift and generates a stop codon located
one codon after the deletion. This alteration yields a truncated CYP2D6*6 protein
that is enzymatically inactive.;
