Association of endothelial lipase genetic polymorphism with lacunar infarction in a Chinese population.

ABSTRACT: INTRODUCTION:This study sought to investigate the correlation between the single nucleotide polymorphism (SNP) rs9958947C>T in the endothelial lipase (LIPG) gene promoter and lacunar infarction in the Han population in China. MATERIALS AND METHODS:A case-control method was applied in this study, which included 378 patients with lacunar infarction in the patient group and 404 healthy individuals who received a routine physical examination in the control group. The polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) methods were used to detect the SNP (rs9958947) in the LIPG promoter for the two groups. RESULTS:The T allele frequency (51.32%) and CT+TT genotype frequency (77.78%) in the patient group were significantly higher than those in the control group (43.32% and 66.34%, respectively). Comparison of the T allele frequency and CT+TT genotype frequency between the two groups showed statistically significant differences. Logistic regression analysis showed that the T allele, male, smoking, hypertension, hyperlipidemia and diabetes were independent risk factors for lacunar infarction in the Han population in China. CONCLUSION:Therefore, we concluded that SNP rs9958947 in the LIPG gene promoter is associated with the incidence of lacunar infarction.

Project description:BackgroundAccumulating evidences have shown that miRNAs are directly or indirectly involved in a variety of biological processes, and closely associated with diverse human diseases, including cardiovascular diseases. SNPs locating within pri/pre-miRNA can affect miRNA processing and binding ability of target genes. MiR-27a, miR-26a-1 miR-100, miR-126 and miR-218 were reported to be associated with pathogenesis of myocardial infarction (MI). Here we aimed to evaluate the potential association of five polymorphisms in these pri/pre-miRNAs with individual susceptibility to MI in a Chinese Han population.MethodsGenotyping was performed in 287 MI cases and 646 control subjects using polymerase chain reaction-ligase detection reaction (PCR-LDR) method. The association of these SNPs with MI risk was performed with SPSS software.ResultsIn a logistic regression analysis, we found that AG heterozygote (OR = 0.40, 95% CI = 0.21-0.76, Pa = 0.005) or AA homozygote (OR = 0.40, 95% CI = 0.22-0.75, Pa = 0.004) of pre-miR-27a rs895819 had a reduced susceptibility to MI in comparison with GG homozygote. Similarly, a reduced risk of MI was detected when the AG and AA genotypes were combined (OR = 0.40, 95% CI = 0.22-0.74, Pa = 0.003). However, no significant association between pri-miR-26a-1 pri-miR-100, pri-miR-126 and pri-miR-218 polymorphisms and MI risk was observed under the allelic and established genetic models. Further stratified analysis of pre-miR-27a rs895819 revealed a more significant association of AG + AA genotypes with MI risk among younger, male and smoking subjects. Interestingly, AG and AA genotypes of the rs895819 polymorphism conferred about 0.17 mmol/L and 0.18 mmol/L increase in HDL-C levels compared to GG genotype.ConclusionsOur findings suggest that the pre-miR-27a rs895819 polymorphism is associated with MI susceptibility in the Chinese Han population, which probably due to influence the HDL-C levels.
