Recent studies have provided evidence that common genetic variations could account for a proportion of leukemia in adult or children. To evaluate the contribution of candidate gene association studies to the understanding of genetic susceptibility to acute lymphoblastic leukemia we conducted a systematic review from published studies. The polymorphisms of genes encoding carcinogen-metabolizi...

I had an “aha!” moment the other day—one of many I’ve experienced while I’ve had the privilege of being President of the College of Family Physicians of Canada. This one was rather bittersweet; it wasn’t one that made me leap for joy or that gave me renewed enthusiasm for my daily work. No, on this occasion the sobering reality that befell me occurred during a dinner with colleagues, at which t...

myocardial infarction (mi) and its major determinant, coronary artery disease (cad), are complex diseases arising from the interaction between several genetic and environmental factors. until recently, the genetic basis of these diseases was poorly understood. genome-wide genetic association studies have afforded a comprehensive insight into the association between genetic variants and diseases...

The number of methods for genome-wide testing of gene-environment (G-E) interactions continues to increase, with the aim of discovering new genetic risk factors and obtaining insight into the disease-gene-environment relationship. The relative performance of these methods, assessed on the basis of family-wise type I error rate and power, depends on underlying disease-gene-environment associatio...
