PLA2G5 and coronary artery disorder: The three PLA2G5 polymorphisms were in strong linkage disequilibrium (D′ > 0.95) and four haplotypes were observed: AGG, CGG, CAG, and CGA. The CGA haplotype was associated with increased risk of premature CAD (OR = 1.49, 95% CI: 1.15–1.93, and P = 0.0023) (Table 4).
