dc.description.abstractObjective: 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 (P<0.0001), respectively. The frequencies of G and A alleles were 61.5% and 38.5% for the control, and 28.5% and 71.5% for the stroke subjects (P<0.0001). Our study shows that the mutant allele of the LIPC promoter was associated with dyslipidemia, lower hepatic lipase activity, and this variation contributed to the increased defective plasma high density lipoprotein-cholesterol (HDL-C), HDL2-C and HDL3-C concentration for both subjects. The control subjects had 6 single nucleotide polymorphism and 6 amino acid substitutions while the stroke subjects had 32 single nucleotide polymorphism and 20 amino acid substitutions. Conclusions: LIPC –250G>A polymorphism can influence plasma lipid profiles and lipoprotein ratios in patients with ischemic stroke.en_US
