Abstract:


Background: Large-scale population studies showed that the SNP rs1764391 of Connexin37 gene also known as Cx37 gene may play a pivotal role in the occurrence and development of acute myocardial infarction (AMI). Published results, however, are highly controversial.

Objective: This study aimed to examine the association between SNP rs1764391 of Cx37 and diseasesusceptibility, several risk factors, and gene-environment interactions of AMI in Guangxi Han Chinese population.

Methods: In this study, 344 healthy controls and 344 AMI patients of Han Chinese population were enrolled. The TaqMan assay was implemented to identify genotypes of Cx37 and allele frequencies of SNP rs1764391 in both the AMI and control groups.

Results: Significant differences were detected in TT genotype frequencies of SNP rs1764391 between the AMI and control groups (P < 0.05). In the context of gender stratification, the result was also statistically different in women (P < 0.05). Each variable such as age, BMI, diabetes, high blood pressure, smoking and TC was a risk factor and correlated significantly (P < 0.05) with the development of AMI. HDL-C correlated negatively with the risk of AMI (P < 0.001). BMI, smoking or alcohol consumed interacts significantly (P < 0.017) with the presence of the SNP rs1764391 CC genotype.

Conclusion: Evidences were presented that Cx37 rs1764391 variation may contribute to the risk for AMI, especially in women and this genetic variant may prove to be a potential biomarker for AMI risk stratification and may prove to be a useful target for therapeutic intervention to further improve prognosis in high-risk patients.
