Abstract

We examined the association of variation in the type 2 diabetes risk-conferring TCF7L2 gene with the risk of incident coronary heart disease CHD among the lean, overweight, and obese members of the Atherosclerosis Risk in Communities ARIC Study cohort. Cox proportional hazard regression analyses were performed using a general model, with the major homozygote as the reference category. For 9,865 whites, a significant increase in the risk of CHD was seen only among lean  kg- individuals homozygous for the allele of the TCF7L2 rs7903146 gene risk variant hazard ratio 1.42; 95% CI 1.03,1.97; . No association was found among 3,631 blacks, regardless of BMI status. An attenuated hazard ratio was observed among the nondiabetic ARIC cohort members. This study suggests that body mass modifies the association of the TCF7L2 rs7903146 T allele with CHD risk.
