The Promoter Polymorphism rs3918226 of the Endothelial Nitric Oxide Synthase Gene as a Novel Susceptibility Marker for Peripheral Artery Disease.

Background: This pilot study aimed to investigate the association between the single nucleotide polymorphism (SNP) rs3918226 in the promoter of the nitric oxide synthase (NOS3) gene and the risk of peripheral artery disease (PAD).

Methods: DNA samples from 1,263 unrelated subjects of Slavic origin, including 620 patients with PAD and 643 controls, were genotyped for the SNP rs3918226 using the MassArray-4 system.

Results: The rs3918226 polymorphism was found to be strongly associated with an increased risk of PAD regardless of coronary artery disease, hypertension, or cigarette smoking (odds ratio [OR] = 2.

Lipid-Associated GWAS Loci Predict Antiatherogenic Effects of Rosuvastatin in Patients with Coronary Artery Disease.

We have shown that lipid-associated loci discovered by genome-wide association studies (GWAS) have pleiotropic effects on lipid metabolism, carotid intima-media thickness (CIMT), and CAD risk. Here, we investigated the impact of lipid-associated GWAS loci on the efficacy of rosuvastatin therapy in terms of changes in plasma lipid levels and CIMT. The study comprised 116 CAD patients with hypercholesterolemia.

Comprehensive Statistical and Bioinformatics Analysis in the Deciphering of Putative Mechanisms by Which Lipid-Associated GWAS Loci Contribute to Coronary Artery Disease.

The study was designed to evaluate putative mechanisms by which lipid-associated loci identified by genome-wide association studies (GWAS) are involved in the molecular pathogenesis of coronary artery disease (CAD) using a comprehensive statistical and bioinformatics analysis. A total of 1700 unrelated individuals of Slavic origin from the Central Russia, including 991 CAD patients and 709 healthy controls were examined. Sixteen lipid-associated GWAS loci were selected from European studies and genotyped using the MassArray-4 system.

Pharmacogenetic loci for rosuvastatin are associated with intima-media thickness change and coronary artery disease risk.

Polymorphisms at , , , , and are attractive targets for assessment of their impact on lipid-lowering therapy with rosuvastatin. The present study investigated whether polymorphisms at these genes are associated with the risk of coronary artery disease (CAD) development, and reduction of atherogenic lipids and carotid intima-media thickness (CIMT) in CAD patients, taking rosuvastatin. 190 CAD patients and 1697 subjects were enrolled in pharmacogenetic and genetic association study, respectively.
