rs662799 is a SNP in the APOA5 gene. The rarer rs662799(C) allele has been associated in multiple reports (cited below) to be associated with higher triglyceride levels.
Independently of triglyceride levels, perhaps, a study based on 1,864 Italian patients <45 years old at the time of their first heart attack (myocardial infarction) concluded that this SNP is associated with higher risk for an early heart attack, with a per C allele odds ratio of 1.44 (CI: 1.23-1.69, p = 6.7 × 10(-5)).[PMID 21130994]
This SNP has also been reported to help prevent weight gain from high fat diets.
[PMID 17211608] 1,073 men and 1,207 women participating in the Framingham Offspring Study rs662799 -1131T>C in modulates the effect of fat intake on BMI and obesity risk in both men and women. Individuals with at least one C allele gained significantly less weight on a high fat diet than those homozygous for the T allele.
