 Apolipoprotein C3 (APOC3) plays an important role in regulating lipid levels. This study aimed to assess whether the polymorphism APOC3-rs2854116 is associated with lipid profiles in primary school children in Hanoi. A case-control study was designed including 161 cases with dyslipidemia and 406 controls without dyslipidemia. Genotype for APOC3-rs2854116 polymorphism was determined by the polymerase chain reaction and restriction fragment length polymorphism method (PCR-RFLP). The results showed that there were differences in the effect of APOC3-rs2854116 polymorphism to lipid profiles among children with dyslipidemia. In comparison with A/G and A/A carriers, the G/G carriers had the higher concentration of serum TC, TG, and LDL-C (P < 0.05). APOC3-rs2854116 polymorphism was related to hypercholesterolemia in children with the most appropriate genetic model being additive model. Increasing each of the G alleles increased the risk of hypercholesterolemia by 2.2 times (P = 0.005) after adjustment for age and sex. This relationship was almost unchanged after adjustment for obesity-related traits. The study suggested that the APOC3-rs2854116 polymorphism significantly associated with hypercholesterolemia in primary school children in Hanoi independent of obesity-related traits.
