The genetics of human drug response

Abstract

The genetics of variable drug response appears to be a more tractable complex trait than common disease predisposition. This has implications for prioritizing research and for experimental design, and in particular argues for extensive use of candidate gene based approaches in pharmacogenetic association studies. Eventually, when whole genome scanning becomes feasible, it may be appropriate to consider weighting schemes that assign higher prior probabilities of variants in genes related to the mode of action of metabolism of medicines.
