Abstract:
Objective To investigate the association of the LIPC-C480T (rs1800588) and lipid levels and dyslipidemia in different age-and-sex groups in Han Chinese population.Methods The serum TC,TG,LDL-C and HDL-C were detected by automatic biochemical analyzer in 2420 health adults (1527 men and 893 women).The genotypes of rs1800588 were detected by M ALDI-TOF MS.According to the age difference (≤44,45-59 and ≥60-year-old),the total samples were divided to young (241 men and 201 women),middle-aged (652 men and 360 women) and older (634 men and 332 women) groups.The effects of genotypes on 4 serum lipid indicators in each age-and-gender group were analyzed by one way analysis of variance (ANOVA),and the odd risk of genotypes on dyslipidemia was estimated by binary Logistic regression analysis.The P value less than 0.05 was considered statistically significant.Results The frequence of allele T for LIPC rs1800588 in this population is 39.4％.In each age group the lipid parameters are quite different between males and females.Compared with those with CC genotype,middle-aged and elder men with CT or TT genotype have higher TC and HDL-C levels,and elder men with TT genotype also have higher TC level ; young women bearing CT genotype have higher TC level,and the CT and TT genotypes have higher HDL-C levels,middle aged women with CT or TT genotype have higher TC and TG levels,and CT genotype also have higher HDL-C level,the elder women with TT genotype have higher HDL-C level.Compared with those CC genotype individuals,the risk for mixed hyperlipidemia and hypercholesterolemia increases 2.318 folds (P =0.004) and 2.571 folds (P ＜ 0.001) respectively,while the risk for low HDL-C decreases 1.908 folds (P =0.029) for TT genotypes individuals among elder males; the hypercholesterolemia risk increasc 1.688 (P =0.036) and 2.099 times (P =0.040) in CT and TT genotypes respectively,and the risks for hypertriglyceridemia and mixed hyperlipidemia are 2.060 (P =0.038) and 2.381 (P =0.019) times higher than those with CC genotype among middle-aged females.Conclusions The LIPC rs1800588 site associates with the lipid levels and dyslipidmia risk in Han Chinese in an age-and-sex model.This SNP site has higher impact on lipid levels and dyslipidemia among elder males and middle-aged females,and the T allele is the risk factor.
