The Ile462Val AG variant and combined AG and GG variant was significantly associated with VTE, adjusted for age, gender, weight and contraceptives (OR=1.362, 95%CI 1.026, 1.809, p=0.033; OR=1.420, 95% CI 1.081, 1.865, p=0.012, respectively); The AG and GG combined variant was still significantly associated with VTE when adjusting further for smoking (OR=1.344, 95%CI 1.019,1.772, p=0.036) A more than two-fold increase for VTE was associated with the Ile462Val combined variant of AG+GG (OR of 2.805, 95% CI 1.250, 6.293, p=0.012) in the smokers.
