Hepatic lipase gene -514C/T polymorphism in the Guangxi Hei Yi Zhuang and Han populations.
Hei Yi Zhuang is an isolated subgroup of the Zhuang minority in China. This study was designed to compare the difference in the hepatic lipase gene (LIPC) -514C/T polymorphism and its association with lipid profiles between the Guangxi Hei Yi Zhuang and Han populations. Genotyping of the LIPC -514C/T was performed in 873 subjects of Hei Yi Zhuang and 867 participants of Han Chinese. The frequency of -514T allele was 43.47% in Hei Yi Zhuang, and 36.10% in Han (P < 0.001). The frequencies of CC, CT and TT genotypes were 30.01, 53.04 and 16.95% in Hei Yi Zhuang, and 40.95, 45.91 and 13.14% in Han (P < 0.001); respectively. Serum high-density lipoprotein cholesterol (HDL-C) and apolipoprotein B levels in both ethnic groups were higher in LIPC -514T carriers than in C carriers. In addition, serum triglyceride levels in Han were higher in TT genotype individuals than in CC genotype subjects (P < 0.05). Serum HDL-C levels were positively correlated with age, alcohol consumption and LIPC -514C/T genotypes, and negatively associated with hypertension and cigarette smoking in Hei Yi Zhuang (P < 0.05-0.01), whereas HDL-C levels were positively correlated with age, alcohol consumption and LIPC -514C/T genotypes, and negatively associated with body mass index and cigarette smoking in Han (P < 0.05-0.001). The differences in serum HDL-C levels between the two ethnic groups might partially attribute to the differences in the LIPC -514C/T polymorphism.
