Pharmacogenetics is defined as?

• A. Pharmacogenetics is the study of how people's genetic variations correlate with their responses to a specific medication
• B. Pharmacogenetics is the study of environmental factors affecting drug response
• C. Pharmacogenetics is the study of how drugs affect the genome
• D. Pharmacogenetics is a field focusing on drug manufacturing

Answer: (A)

Pharmacogenetics focuses on how a person’s genetic makeup influences their response to a given medication. Genetic variations can change how a drug is metabolized, how well it works, and the risk of adverse effects, so different individuals may have different outcomes from the same drug dose. This directly describes the idea of correlating genetic variations with responses to a specific medication, which is why this option fits best. The other concepts involve environmental factors, how drugs might affect the genome, or manufacturing, none of which capture the gene–drug response relationship central to pharmacogenetics.
