Background Metabolic syndrome consists of multiple risk factors that are increasing the cardiovascular mortality. The T-1131C variant of the apolipoprotein A5 gene, associated with increased triglycerides, has been found to confer risk for cardiovascular diseases and metabolic syndrome. Because other naturally occurring variants of the gene also correlate with elevated triglycerides, the possible role of 2 common variants, the IVS3+G476A and T1259C, with metabolic syndrome was investigated. Methods and Results A total of 213 metabolic syndrome patients and 142 healthy controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism. Serum triglycerides were increased in carriers compared with non-carriers in both groups (p<0.001); serum cholesterol levels were similar in all genotypes. The IVS3+476A allele frequency was increased in metabolic syndrome patients compared with controls (8.05 vs 2.47%; p<0.05), whereas the 1259C allele frequency did not differ between the groups. Multiple logistic regression analyses adjusted for age, gender, serum total cholesterol, acute myocardial infarction and stroke revealed that the IVS3+476A variant confers risk for development of metabolic syndrome (odds ratio=3.529, 95% confidence interval 1.308-9.029, p=0.009), but the 1259C allele had no such an effect. Conclusions Carrying the IVS3+473A allele is associated with elevated triglycerides and confers risk for development of metabolic syndrome, a combination that represents increased risk for development of atherogenic vascular diseases.
