摘要：We conducted a cross-sectional study in a Spanish population (n = 1,029) to investigate associations between the LPL and APOC3 gene loci (LPL - Hind III, LPL -S447X, and APOC3 - Sst I) and plasma lipid levels and their interaction with APOE polymorphisms and smoking. Carriers of the H⁻ or the X447 allele had higher levels of HDL cholesterol (HDL-C), and lower levels of TG, after adjustment for age, body mass index, alcohol, smoking, exercise, and education ( P APOC3 polymorphism presented additive effects to the LPL variants on TG and HDL-C levels in men, and on TG in women. The most and the least favorable haplotype combinations were H⁻/X447/S1 and H⁺/S447/S2, respectively. These combinations accounted for 7% and 5% of the variation in HDL-C and TG in men, and 3% and 4% in women. There was a significant interaction between APOE and LPL variants and HDL-C levels in both genders ( P Hind III- APOE -smoking, P = 0.019), indicating that smoking abolished the increase in HDL-C levels observed in ε4/H⁻ subjects. Understanding this gene-gene-environmental interaction may facilitate preventive interventions to reduce coronary artery disease risk. —Corella, D., M. Guillén, C. Sáiz, O. Portolés, A. Sabater, J.
