However, the The combination of inherited alleles is a from gene duplication. There is strong evidence that certain genetic variants may affect the metabolism of efavirenz (Sustiva®), bupropion (Wellbutrin SR®), and methadone (Dolophine®). Members: Your genotype for rs5030656 is —. For research use only. than two copies of the CYP2D6 gene (gene duplication) or absence of ultra-rapid extensive metabolizers (UMs). Because of inherited (genetic) traits that cause variations in these enzymes, medications may affect each person differently.Drug-gene testing — also called pharmacogenomics or pharmacogenetics — is the study of how genes affect your body's response to medication. The xTAG® CYP2D6 Kit v3 is a qualitative genotyping assay, which can be used as an aid to clinicians in determining therapeutic stategy for therapeutics that are metabolized by the CYP2D6 gene product. One of these CYP enzymes, CYP2D6, is responsible for the metabolism and elimination of approximately 25% of clinically used drugs1.
