Introduction: Genetic load may indirectly influence on cardiovascular risk. This work aimed to analyze the influence of polymorphisms (APOA5 C56G-Ser19Trp, Prothrombin-G20210A, F5 Arg506Gln, MTHFR-C677T, LIPC-C-514T, LPA-I4300M, PPAR_ALPHA-L162V, APOA5-1131T > C, APOE-APOE2/3/4, and APOE-APOE2,3,4) in plasma triglyceride (TG) levels of patients ingesting plant sterols. Materials and Methods: Double-blind, crossover, controlled clinical trial was performed in 45 individuals (25 women). About 2.24 g sterols in milk and placebo milk were ingested daily during 3 weeks each, separated by a 2-week washout period. Blood draws and saliva genomic DNA was extracted. Results: APOA5-C56G-Ser19Trp, MTHFR-C677T, and PPAR_ALPHA-L162V greatly benefit from sterols intake. APOA5-C56G-Ser19Trp GG homozygous carriers lowered their TGs more than CG heterozygote carriers (P = 0.003). TT homozygous carriers of gene LIPC C-514T experienced an increase of TGs. Conclusions: Further studies are needed to establish which genotype combinations is the most protective against hypertriglyceridemia.
