The –250G>A polymorphism in the hepatic lipase gene promoter influences plasma lipid profile and lipoprotein ratio in patients with ischemic stroke

Abstract

Objective: To evaluate the influence of –250G>A (rs2070895) polymorphism in hepatic lipase gene (LIPC) promoter on plasma lipid parameters of ischemic stroke patients. Methods: A total of 100 stroke patients and 100 control subjects matched for sex (59 men and 41 women) and age were selected. Hepatic lipase activity and lipid profiles were measured while lipoprotein ratios were calculated. Genotyping of the –250G>A promoter polymorphism of the LIPC was performed by the polymerase chain reaction and restriction fragment length polymorphism method combined with 2% gel electrophoresis and then confirmed by direct sequencing. The LIPC promoter gene sequencing data were compared with refseqNG011465.1 LIPC from GenBank. Results: The frequencies of GG, GA and AA genotypes of LIPC rs2070895 polymorphism were 39%, 45% and 16% for the control, 10%, 37% and 53% for the stroke subjects (PA polymorphism can influence plasma lipid profiles and lipoprotein ratios in patients with ischemic stroke.
