CYP Enzyme Polymorphisms

Meaning

Genetic variations, or polymorphisms, within the genes that encode the Cytochrome P450 (CYP) family of enzymes, which are critical for the metabolism and detoxification of hormones, drugs, and xenobiotics. These genetic differences result in altered enzyme activity, classifying individuals as poor, intermediate, extensive, or ultra-rapid metabolizers. Understanding these polymorphisms is essential in personalized medicine for optimizing hormonal therapy dosages and predicting individual metabolic clearance rates.
