Endothelial lipase (LIPG) is a member of the triglyceride lipase family which includes hepatic lipase and lipoprotein lipase. Its activity is related to clinically important parameters like blood lipid levels, hypertension, and obesity. In this work, we investigated the association of a LIPG promoter polymorphism, rs9958947C>T, with susceptibility to ischemic stroke in a Korean population. A total of 1,144 subjects (656 cerebral infarction patients and 488 controls) were enrolled on a voluntary basis. The rs9958947C>T polymorphism was genotyped using the single-base extension method. The association of rs9958947C>T with disease status was evaluated by statistical analyses. The frequencies of the rs9958947 C and T alleles were significantly different between the stroke patient group and control group (OR [95% CI], 1.300 [1.000?1.691], P=0.0449). A significantly higher frequency of the CT+TT genotype was observed in the patient group compared to the control group (CC/CT+TT, OR [95% CI], 1.632 [1.094?2.435], P=0.0164). The results suggest that the T allele of the LIPG promoter polymorphism rs9958947C>T should be considered as a genetic risk factor for ischemic stroke. Further association studies in other ethnic populations would help to generalize this hypothesis.
