Pharmacogenomic Variants

**Definition:** Naturally occurring genetic variations associated with drug response (e.g., dosage, extent and rate of metabolic processes). While these variants are not markers for GENETIC PREDISPOSITION TO DISEASE they influence PHARMACOKINETICS and pharmacodynamics and often occur on genes encoding drug metabolism enzymes and transporters (e.g., ANGIOTENSIN CONVERTING ENZYME; CYTOCHROME P-450 CYP2D6).
