Variable Drug Response: Genetic Evaluation

Pharmacogenetics is the study of genetic variation in response to drugs. Although there is some evidence that drug response genotypes cluster in ethnic groups, this effect is less important than individual variation.

Keywords: pharmacogenetics; pharmacogenomics; drug evaluation; population differentiation; medical genetics; quantitative traits; association studies
