С(-344)Т polymorphism of aldosterone synthase gene, risk of metabolic syndrome, and atrial fibrillation risk for inhabitants of the Northwest regions of Russia

Objective: to estimate contribution of C(-344)T version of aldosterone synthase CYP11B2 gene in risk of metabolic syndrome (MS) and atrial fibrillation (AF) for inhabitants of the Northwest region of Russia. Material and methods: 199 patients with MS, 103 from them with AF and 267 healthy persons. Identification of C-344T gene of CYP11B2 aldosterone sinthase has been performed by means of PCR method with restriction analysis. Results: in MS carriership of TT (-344) genotype met more often than in control: 33.2 % and 24.3 %, respectively (p = 0.04). Carriership of TT (-344) genotype increases risk of MS: OR = 1.54 (95 % CI 1.03-2.32) and was not associated with an increased risk of AF. Conclusion: association of TT(-344) genotype of CYP11B2 gene with risk of metabolic syndrome for inhabitants of the Northwest region ofRussia is revealed.
