Precision medicine, which tries to personalize medical therapy to each individual or group of individuals, is exemplified by pharmacogenomics. Pharmacogenomics is the study of how your DNA influences your pharmacological response. Pharmacogenomics is the study of how medicine interacts with genes that are passed down through generations. This includes the impact of inherited genes on how drugs operate for each individual. Correlating individual genetic variation with pharmacological reactions is an important use of pharmacogenomics. One of the most important aspects of customized treatment is pharmacogenomics.
