Abstract:
OBJECTIVETo study the distribution of ScrF1 restriction polymorphism in intron 2 of the 3-hydroxy-3-methylglutaryl coenzyme A(HMG-CoA) reductase gene in Chinese Han population and the association of the polymorphism with coronary heart disease(CHD).
METHODSHMG-CoA reductase genotyping was performed using polymerase chain reaction-restriction fragment polymorphism.
RESULTSHMG-CoA reductase allelic frequencies of A, a were 0.519, 0.481; 0.440, 0.560 in CHD group and control group respectively. There was no significant difference in frequencies of allele and genotype in ScrF1 polymorphism between CHD group and control group(P>0.05). However, the levels of plasma very low density lipoprotein (VLDL) and TG in CHD patients with AA genotype were higher than those in CHD patients with other genotypes(P<0.05). The frequencies of A, a alleles at ScrF1 polymorphic site were significantly different from those reported in European Caucasians (0.44 vs 0.55, 0.56 vs 0.45, P<0.05).
CONCLUSIONNo direct association was found between the ScrF1 polymorphism and CHD, but there is a significant correlation between the AA genotype of the HMG-CoA reductase gene and the levels of plasma VLDL and TG in CHD group.
