Warfarin Pharmacogenetics: An Illustration of the Importance of Studies in Minority Populations

Clinical Pharmacology & Therapeutics – Translation of pharmacogenetics to clinical practice is increasingly common. However, most data arise in people of European ancestry, so clinical translation in non-Europeans can be challenging. Depending on the population being assessed, a polymorphism’s effect can differ in magniture or be absent. Studies in minorities are therefore essential as they present opportunities for discovery that would be missed through European-only studies, and they ensure that all populations benefit from clinical pharmacogenetics.
