Essential hypertension is considered to be caused by a complicated combination of genetic and environmental factors. Alterations of lipid metabolism in plasma have been reported to be related to an increased risk of essential hypertension. The purpose of this study was to investigate the relationship between two genetic polymorphisms (Pvu II and Hind III RELPs) of the human lipoprotein lipase (LPL) gene and essential hypertension in korean population. In our result the Pvu II RFLP of LPL gene was significantly associated with essential hypertension (P < 0.05). Therefore, we suggest that the Pvu II RFLP of LPL gene may be useful as a genetic marker for essential hypertension in Korean population.

Lipoprotein lipase (LPL) plays an essential role in the regulation of high-density lipoprotein cholesterol (HDLC) and triglyceride levels, which have been closely associated with cardiovascular diseases. Genetic studies in European have shown that LPL single-nucleotide polymorphisms (SNPs) are strongly associated with lipid levels. However, studies about the influence of interactions between LPL SNPs and lifestyle factors have not been sufficiently performed. Here, we examine if LPL polymorphisms, as well as their interaction with lifestyle factors, influence lipid concentrations in a Korean population. A two-stage association study was performed using genotype data for SNPs on the LPL gene, including the 3' flanking region from 7,536 (stage 1) and 3,703 (stage 2) individuals. The association study showed that 15 SNPs and 4 haplotypes were strongly associated with HDLC (lowest $p=2.86{\times}10^{-22}$) and triglyceride levels (lowest $p=3.0{\times}10^{-15}$). Interactions between LPL polymorphisms and lifestyle factors (lowest $p=9.6{\times}10^{-4}$) were also observed on lipid concentrations. These findings suggest that there are interaction effects of LPL polymorphisms with lifestyle variables, including energy intake, fat intake, smoking, and alcohol consumption, as well as effects of LPL polymorphisms themselves, on lipid concentrations in a Korean population.
