BACKGROUND AND OBJECTIVES Warfarin inhibits vitamin K epoxide reductase, of which microsomal epoxide hydrolase is a putative member. Several studies have found signals of association with warfarin maintenance dose in the EPHX1 gene. The aim of this study was to determine the effects of EPHX1 variants on warfarin maintenance dose in a multiethnic Asian(More)
AIM We aimed to estimate the population impact of warfarin pharmacogenetic testing (WPGT) across multiple populations. MATERIALS & METHODS We used the expanded International Warfarin Pharmacogenetics Consortium data set and genotype frequencies from HapMap to simulate dose distributions for each CYP2C9/VKORC1 genotype combination in the different races,(More)
A major goal of the field of pharmacogenomics is to identify the genomic causes of serious adverse drug reactions (ADRs). Increasingly, genome-wide association studies (GWAS) have been used to achieve this goal. In this article, we review recent progress in the identification of genetic variants associated with ADRs using GWAS and discuss emerging themes(More)
The design of molecules to fit into the active site of receptors is a rapidly developing area of pharmacology and medicinal chemistry. A good ligand needs a suitable geometry and also appropriate electrostatic properties. The electrostatic properties of the ligand should complement those of the receptor. We present a method for the assignment of(More)
