Abstract :

Lipoprotein-associated phospholipase A2 (Lp-PLA2) plays an important role in coronary heart disease (CHD). This study was aimed to investigate the associations of polymorphisms (R92H, V279F, I198T, and A379V) in PLA2G7 with CHD. A total of 322 patients with CHD and 414 CHD-free controls were included in the study. Polymorphisms in PLA2G7 were sequenced by DNA Sequencer and statistical analyses were performed to study the associations between polymorphisms and CHD. RH + HH genotype, RH genotype, and H allele of R92H were significantly associated with an increased risk of CHD (P = 0.005, P = 0.009, and P = 0.003, respectively), while no associations were observed between V279F and I198T and CHD (A379V was not analyzed because of deviation from Hardy-Weinberg equilibrium). Correlations between R92H and CHD still existed after adjustment for confounding risk factors of CHD (P = 0.001). Furthermore, stratified analyses showed subgroups of the senior, hypertension, non-smoking, non-diabetics, and male subjects brought a higher risk for CHD (P = 0.015, P = 0.001, P = 0.001, P = 0.002, and P = 0.004, respectively). We also observed a lower level of protective factor HDL-C in CHD patients carrying genotype RH + HH than patients with RR (P = 0.047). Furthermore, we conducted haplotype analysis and detected more harmful effects of haplotypes HVI and RVT as compared with other haplotypes (P = 2.538 x 10(-3) and P = 0.031). These findings indicated that R92H variant in PLA2G7 gene might contribute to CHD susceptibility in a southern Chinese population.
