Abstract: | The study sought an association between the G1691A factor V point mutation and factor VII Arg/Gln(353) gene polymorphism and premature coronary artery disease (CAD), and the interactive effect on CAD risk between the G1691A factor V point mutation and factor VII Arg/Gln(353) gene polymorphism as well as between tested polymorphisms and traditional risk factors. 167 patients with CAD younger than 55 years were compared with 132 healthy subjects. The frequency of factor V point mutation was 7.8 % among Slovene patients with premature CAD, and 4.5 % among controls. No association was found between either the factor V point mutation (AG genotype) or M1M1 genotype of factor VII Arg/Gln(353) gene polymorphism and the risk of CAD in Slovenia using univariate analysis (factor V point mutation: OR = 1.8, 95% CI = 0.7-4.9; p = 0.25; factor VII Arg/Gln(353) gene polymorphism: OR = 1, 95 % CI = 0.6-1.7; p = 0.9). However, a joint effect on the risk of CAD was found between factor V point mutation (AG genotype) and M1M1 genotype (OR = 3.6, 95 % CI = 1-12.9; p = 0.03). Additionally, an interactive effect on CAD risk was found between AG genotype and metabolic risk factors (OR = 3.8, 95% CI = 1.1-13.6; p = 0.03). In conclusion, we provide evidence for a joint effect on CAD risk between G1691A factor V point mutation and factor VII Arg/Gln(353) gene polymorphism as well as between factor V point mutation and metabolic risk factors. |
