Abstract: | AIM: To investigate the association of endothelial lipase gene (LIPG) Thr111Ile and Gly26Ser polymorphism with lipoprotein in patients with coronary heart disease (CHD) in Chinese.METHODS: 438 patients were classified as 242 CHD group and 196 controls group by selective coronary angiography.Plasma level of lipoprotein was determined and the Thr111Ile and Gly26Ser polymorphism was screened by PCR-RELP.RESULTS: The frequencies of Thr111Ile genotype in Chinese were CC 76.7%,CT 23.3%,TT 0.0%.The frequencies of allele were C 88.3%,T 11.7%.The plasma level of HDL-c in CT group was significantly higher than that in CC group (P<0.05) on logistic regression analysis.However,logistic regression analysis revealed that there was no significant difference between CHD group and control group for Thr111Ile polymorphism (P>0.05).No Gly26Ser mutation was observed in this study.CONCLUSION: The polymorphism of Thr111Ile is present in patients with CHD in Chinese,and T allele is related to high HDL-c level.There is no significant association between the polymorphism of Thr111Ile and CHD.The Gly26Ser mutation has not found in this study. |
