What is Pharmacogenetics and Genomics?

Pharmacogenomics is the study of how genes affect a person’s response to drugs. This field combines pharmacology (the science of drugs) and genomics (the study of genes and their functions) to develop effective, safe medications that can be prescribed based on a person’s genetic makeup.

What is the difference between pharmacogenetics and pharmacogenomics?

Pharmacogenetics is the study of genetic causes of individual variations in drug response whereas pharmacogenomics deals with the simultaneous impact of multiple mutations in the genome that may determine the patient’s response to drug therapy.

What is pharmacogenomics PPT?

GENOMICS Pharmacogenetics is often a study of the variations in a targeted gene, or group of functionally related genes for variability in drug response Refers to how variation in one single gene influences the response to a single drug Pharmacogenomics is the use of genetic information to guide the choice of drug …

How accurate is pharmacogenetic testing?

Only 36% of the labels reviewed provided convincing evidence for the clinical validity of the pharmacogenetic test, that is, an established association between the pharmacogenetic variant and drug response; and only 15% provided convincing evidence of clinical utility, that is, one or more controlled studies …

What is an example of pharmacogenetics?

Example: Depression and Amitriptyline. The breakdown of the antidepressant drug amitriptyline is influenced by two genes called CYP2D6 and CYP2C19. If your doctor prescribes amitriptyline, he or she might recommend genetic testing for the CYP2D6 and CYP2C19 genes to help decide what dose of the drug you need.

Is pharmacogenomics used today?

One current use of pharmacogenomics involves people infected with the human immunodeficiency virus (HIV). Before prescribing the antiviral drug abacavir (Ziagen), doctors now routinely test HIV-infected patients for a genetic variant that makes them more likely to have a bad reaction to the drug.

What is the main objective of pharmacogenomic studies?

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.

What is an example of pharmacogenomics?

What technology is used in pharmacogenetics?

At the time of development of the first PGx guideline, only Sanger-based sequencing techniques and SNV (single nucleotide variant) arrays were available as methods for variant identification. To date, SNV panel testing remains the most commonly used technology in clinical practice.

Who benefits from pharmacogenetic testing?

Pharmacogenomic testing can help doctors decide which medications to use. An individual’s genes may help determine which medications to avoid or how to adjust the dose of a medication allowing a doctor to tailor medications to a patient based on differences in the patient’s genes.
