Web•What is Genetic Polymorphism? Genetic differences in drug metabolism are the result of genetically based variation in alleles for genes that code for enzymes responsible for the metabolism of drugs. In polymorphisms, the genes contain abnormal pairs or multiples or abnormal alleles leading to altered enzyme function.
