WebCYP2D6 activity is highly variably ranging from no activity in so-called poor metabolizers to ultrarapid metabolism at the other end of the extreme of the activity distribution. A large portion of this variability can be explained by the highly polymorphic nature of the CYP2D6 gene locus for which > 100 variants and subvariants identified to date. The CYP2D6 function in any particular subject may be described as one of the following: [12] poor metabolizer – little or no CYP2D6 function intermediate metabolizers – metabolize drugs at a rate somewhere between the poor and extensive metabolizers extensive metabolizer – normal CYP2D6 … See more Cytochrome P450 2D6 (CYP2D6) is an enzyme that in humans is encoded by the CYP2D6 gene.
