Summary

Pharmacogenomics evolved from pharmacogenetics, recognizing that drug responses are multifactorial, influenced by genes and environment. This science enables personalized medicine for safer, more effective drug use tailored to individual genetic profiles.

Area of Science:

Pharmacogenomics
Genomics
Personalized Medicine

Background:

Pharmacogenetics emerged from clinical observations of genetic influences on drug response.
Systemic studies revealed population-specific pharmacogenetic differences and multifactorial causes of drug response variability.

Observation:

Early observations linked genetic alterations to drug response.
The concept evolved through case studies to encompass population-wide genetic variations.

Findings:

Most drug-response differences are multifactorial, involving multiple genes and environmental factors.
Gene expression variability significantly impacts drug action, shifting research focus to drug effects on genes.

Implications:
