Objective: The correlation of the BRG1 rs1122608 single nucleotide polymorphism (SNP) with acute myocardial infarction (AMI) has been reportedin American and European populations. However, whether rs1122608 acts as a protective factor or a risk factor for AMI is controversial.In this study, we aimed to detect the associations between rs1122608 and the clinical characteristics of AMI as well as susceptibility, gene–environmentinteractions, and risk factors for AMI in a Chinese Han population.Methods: In this study, 300 AMI patients and 300 healthy controls of Chinese Han ancestry were enrolled. PCR-RFLP was used to genotypers1122608 SNPs. Genotypic and allelic frequencies of rs1122608 were compared between the AMI and control groups and among four AMIsubgroups, which were subdivided by typical symptom, diagnosis time (DT), infarction location andserious complication.Results: Significant differences were detected between the AMI patients and the controls in both the genotypic and allelic frequencies ofrs1122608 (p<0.001 for each). There were also interactions between the subjects with a minor T allele and smoking or alcohol consumption(p<0.001 for each).Conclusion: In the Chinese Han study population, the mutant GT and TT genotypes and minor T allele of rs1122608 were positively correlatedwith the risk of AMI. For the first time, we discovered that the GT genotype of the rs1122608 SNP is significantly correlated with diagnosis time ofAMI. In addition, the interactions between the minor T allele of rs1122608 and smoking or alcohol use and between the rs1122608 CC genotypeand alcohol use appear to increase the risk of AMI.
