ABSTRACT
Pharmacogenetics is the study of genetically determined variations in the response to drugs and toxic agents, and their implications on disease. Recently, the discipline has acquired great relevancy due to the development of non-invasive molecular techniques that identify genetic variants in human beings. There is also a need to explain the individual differences in susceptibility to drug actions and disease risk. Genetic variants can modify the magnitude of a pharmacologic effect, toxicity threshold, secondary effects and drug interactions. There are approximately thirty families of drug-metabolizing enzymes with genetic variants that cause functional alterations and variations in pharmacologic activity. We summarize the general knowledge about genetic variants of biotransformation enzymes, their relationship with cancer risk and the role of ethnicity. Cancer pharmacogenetics is another promising and exciting research area that will explain why people with an almost identical group of genes, have a different susceptibility to cancer, whose etiology has genetic and environmental components.
