Association of GNB3 gene C825T polymorphism with coronary heart disease

Association of GNB3 gene C825T polymorphism with coronary heart disease The C825T polymorphism in the gene encoding the G protein beta 3 subunit (GNB3) causes enhanced G protein activation and the increased in vitro cell proliferation. We investigated the association of gene GNB3 C825T polymorphism with coronary artery disease (CAD) in the Russian population. A total of 313 patients with CAD diagnosed on the basis of clinical studies and coronary angyography were examined. The control group included 132 individuals that lacked clinical CAD symptoms and had matching profile of coronary artery disease risk factors. Blood pressure was measured using standard protocols. Increased levels of diastolic and systolic pressure was observed in both groups. The allele and genotype frequencies of this polimorphic marker were significantly higher in the CAD patients than in control. We found that the frequency of allele C and genotype CC was significantly higher in the CAD patients (OR = 1.55; P = 0.0079; OR = 1.63; P = 0.0215, respectively), which suggests higher risk of this pathology in carriers of allele C and genotype CC. Thus, in the Russian population coronary artery disease is associated with GNB3 allele C and genotype CC. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The C825T polymorphism in the gene encoding the G protein beta 3 subunit (GNB3) causes enhanced G protein activation and the increased in vitro cell proliferation. We investigated the association of gene GNB3 C825T polymorphism with coronary artery disease (CAD) in the Russian population. A total of 313 patients with CAD diagnosed on the basis of clinical studies and coronary angyography were examined. The control group included 132 individuals that lacked clinical CAD symptoms and had matching profile of coronary artery disease risk factors. Blood pressure was measured using standard protocols. Increased levels of diastolic and systolic pressure was observed in both groups. The allele and genotype frequencies of this polimorphic marker were significantly higher in the CAD patients than in control. We found that the frequency of allele C and genotype CC was significantly higher in the CAD patients (OR = 1.55; P = 0.0079; OR = 1.63; P = 0.0215, respectively), which suggests higher risk of this pathology in carriers of allele C and genotype CC. Thus, in the Russian population coronary artery disease is associated with GNB3 allele C and genotype CC.
