Relationship Between Polymorphism of Adiponectin Gene SNPS+276 and Coronary Heart Disease

Abstract

Background: This study aims to investigate the relationship between polymorphism of adiponectin (ADIPOQ) gene SNPS+276 and the severity of coronary heart disease (CHD) and coronary artery disease (CAD).

Methods: A total of 582 inpatients were enrolled and divided into Group CHD (342 cases) and the control group (CON, 240 cases), according to their angiographic results from June 2014 to April 2016 for the genotype (G/T) analysis of ADIPOQ SNPs+276 by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

Results: Group CHD: GG 110 (32%), GT 205 (59%), and TT27 (8%); Group CON: GG 36 (15%), GT 161 (67%), and TT 43 (18%) (P < .05). The frequency of allele G in group CHD was 62.1% and 48.5% in group CON (P < .05). The frequencies of genotype GG, GT, and TT were 67 (33.3%), 107 (53.2%), and 27 (13.5%), respectively, in the group with single vascular lesion, and 64 (45.4%), 53 (37.6%), and 24 (17%), respectively, in the group with multiple vascular lesions. There was statistical significance between the two groups (P < .05).

Conclusions: The 276G gene of adiponectin may be a susceptibility gene of CHD, and the genotype GG may be related to the severity of this disease.
