Toxicogenomics is a scientific tool that involves gathering, interpreting, and archiving data on gene expression and related protein activity in specific cells or tissues of an organism in response to hazardous chemicals. The study of how genes influence a person's medication reaction is known as pharmacogenomics. This relatively new discipline combines pharmacology (drug science) with genomics (the study of genes and their activities) to create effective, safe medicines and dosages that are customised to a person's genetic makeup. The field of pharmacogenomics falls under the category of precision medicine which aims to treat each patient individually.
