Genetic Markers at ANRIL, FTO and 2q36.3 Locus in Czech Patients Undergoing Coronary Artery Bypass Graft Surgery.

Abstract

Coronary artery bypass graft (CABG) surgery is one of the most commonly performed operations worldwide. We compared genotype frequencies of three major cardiovascular disease (CVD)-associated genetic markers (ANRIL, FTO and 2q36.3 locus) between 753 patients who underwent CABG at the Institute for Clinical and Experimental Medicine (Prague, Czech Republic) and 2,559 controls from the Czech post-MONICA study. Subjects with at least one major A allele in the rs10757274 polymorphism (ANRIL) were more prevalent in patients after CABG than in the controls (81.7 % vs 72.7 %; OR [95 % CI] 1.67 [1.35-2.05]; P < 0.0001). In contrast, variants within the FTO gene (OR 0.87; 95 % CI, 0.70-1. 09 in a TT vs. GG comparison, P = 0.24) and 2q36.3 locus (OR 1.16; 95% CI, 0.98-1.37 in a +A vs. CC comparison, P = 0.08) were not significantly associated with CVD in our study. Variants were not associated with anthropometric, biochemical, or clinical characteristics within the patient group. Our study suggests that patients with CABG are more commonly carriers of some but not all CVD-associated alleles.
