Abstract

Objective: Variants in hepatic lipase (HL) gene which is a lipolytic enzyme involved in the metabolism of plasma lipoprotein and regulating lipid and lipoprotein metabolism are potential candidate genes for type 2 diabetes. Association of the polymorphisms in the promoter region of the HL gene (LIPC) to the plasma HDL-C concentration has been investigated. In this study, we investigated whether the G-250A polymorphism of LIPC is associated with type 2 diabetes in Chinese Han population.

Subjects and methods: A total of 130 patients with type 2 diabetes and 133 healthy subjects as control were randomly selected from January 2008 to January 2011 in endocrine wards of Zhengzhou People's Hospital. The G-250A polymorphisms were studied by polymerase chain reaction and restriction fragment length polymorphism. A logistic regression analysis was performed to determine the association between the rare allele and type 2 diabetes mellitus.

Results: The frequency of the -250A allele was 0.297 in the T2DM group and 0.388 in the control group (P<0.05), with the difference remaining significant.

Conclusions: Patients who are carrying of the -250A allele in the promoter of the LIPC gene are susceptible to type 2 diabetes mellitus in Chinese Han population.
