Abstract

We determined the contribution of the combination of FEN1 10154G>T with the most significant association in the analysis of plasma arachidonic acid (AA, 20:4 ω6) and the APOA5 -1131T>C on phospholipid ω6PUFA and coronary artery disease (CAD). Patients with CAD (n = 807, 27-81 years of age) and healthy controls (n = 1123) were genotyped for FEN1 10154G>T and APOA5 -1131T>C. We found a significant interaction between these two genes for CAD risk ( P = 0.007) adjusted for confounding factors. APOA5 -1131C allele carriers had a higher CAD risk [odds ratio (OR):1.484, 95% confidence interval (CI):1.31-1.96; P = 0.005] compared with APOA5 -1131TT individuals in the FEN1 10154GG genotype group but not in the FEN1 10154T allele group (OR:1.096, 95%CI:0.84-1.43; P = 0.504). Signifi cant interactions between these two genes were also observed for the AA proportion ( P = 0.04) and the ratio of AA/ linoleic acid (LA, 18:2ω6) ( P = 0.004) in serum phospholipids of controls. The APOA5 -1131C allele was associated with lower AA ( P = 0.027) and AA/LA ( P = 0.014) only in controls carrying the FEN1 10154T allele. In conclusion, the interaction between these genes suggests that the FEN1 10154T variant allele decreases AA and AA/LA in the serum phospholipids of carriers of the APOA5 -1131C allele, but contributes no significant increase in CAD risk for this population subset despite their increased triglylcerides and decreased apoA5.
