How can pharmacogenetics tests be helpful to doctors?

The Pharmacogenomics Program investigates how variations in genes affect response to medications, thereby using a patient’s genetic profile to predict a drug’s efficacy, guide dosage and improve patient safety.

Why is pharmacogenetic testing important?

Pharmacogenetic testing may be used to: Find out whether a certain medicine could be effective for you. Find out what the best dosage might be for you. Predict whether you will have a serious side effect from a medicine.

What is the importance of CYP 2d6?

CYP2D6 is responsible for the metabolism of the second highest number of drugs metabolized by P450 enzymes. Substrates for CYP2D6 can be found in Table 3.1. CYP2D6 is a particularly challenging enzyme to understand and study because of its genetic polymorphism.

What is a pharmacogenetics report?

Pharmacogenetics reports tell you about DNA variants that may influence your body’s ability to process some medications. For example, our reports provide information about certain DNA variants that can affect how well specific drug-metabolizing enzymes work.

What is the purpose of pharmacogenetics?

Pharmacogenomics (sometimes called pharmacogenetics) is a field of research that studies how a person’s genes affect how he or she responds to medications. Its long-term goal is to help doctors select the drugs and doses best suited for each person.

Is pharmacogenomics important in clinical therapeutics?

In clinical studies, pharmacogenetic tests can be used for stratification of patients based on their genotype, which corresponds to their metabolizing capacity. This prevents the occurrence of severe adverse drug reactions and helps in better outcome of clinical trials. This can also reduce attrition of drug compounds.

Which patient would benefit most from pharmacogenetics testing?

One study,31 the Mayo RIGHT study, concluded that preemptive pharmacogenomic testing would benefit most patients, especially those taking multiple medications.

What is the role of pharmacogenetics in rational drug use?

Pharmacogenetics will help to tailor the drug type and its dosage according to the individual’s genotype. It will help to minimize adverse drug reactions as well as cases of non-responders to the drug therapy.

Why is the CYP2D6 genotype not studied in pharmacogenetics?

This is probably due to lack of or a weak indication for genetic testing, and that the CYP2D6 genotype is only one of many factors that determine the individual response to a drug. Pharmacogenetics is often defined as the study of variation in response to drugs due to hereditary factors.

What is the CYP2D6 test?

This CYP2D6 test identifies 25 variants of the more common alleles (*2,*2A,*3-*12,*14,*15,*17,*19,*20,*21,*29,*30,*35,*36,*41,*56,*109), gene deletions, gene duplications and gene rearrangements in PCR-multiplex format, providing increased sensitivity and quality performance.

What percentage of the population is CYP2D6 carrier?

Approximately 4-7% of the population has a slow acting form of this enzyme and 3% a super-fast acting form. About 35% of the population are carriers of a non-functional CYP2D6 allele, which especially elevates the risk of adverse drug events (ADEs) when these individuals are taking multiple drugs.

What drugs are metabolized by CYP2D6?

Drugs that CYP2D6 metabolizes include selective serotonin reuptake inhibitors (SSRI), tricyclic antidepressants (TCA), beta-blockers, opiates, neuroleptics, antiarrhythmics, and a variety of toxic plant substances.
