Resumo
BACKGROUND
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.
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.
CONCLUSIONS
Therefore, we concluded that SNP rs9958947 in the LIPG gene promoter is associated with the incidence of lacunar infarction.
