CYP2D6

Meaning

A specific enzyme within the Cytochrome P450 superfamily, predominantly expressed in the liver, that plays a critical role in the metabolism and detoxification of a large percentage of commonly prescribed therapeutic agents, including antidepressants, antipsychotics, and opioids. Genetic variations in the CYP2D6 gene lead to different enzyme activities, classifying individuals as ultra-rapid, extensive, intermediate, or poor metabolizers. This polymorphism is a key focus of pharmacogenomics.
