We try to explore whether long-term consumption of two healthy dietary patterns (low-fat [LF] diet or Mediterranean diet [MedDiet]) interacts with the apolipoprotein E (APOE) single-nucleotide polymorphisms (SNPs: rs439401, rs440446 and rs7412) modulating postprandial hypertriglyceridemia (ppHTG) in coronary heart disease (CHD) patients.
<b>Results</b>: Three out of 10 eligible SNPs were shown to be associated with risk of ischemic stroke. rs1800947 in <i>CRP</i> gene (additive model: OR = 2.08, 95% CI: 1.00-4.23) and rs1169288 in <i>HNF1A</i> gene (additive model: OR = 1.45, 95% CI: 1.03-2.06) were associated with an increased risk of ischemic stroke. rs440446 in <i>APOE</i> gene (additive model: OR = 0.63, 95%CI: 0.44-0.88) was associated with a decreased risk of ischemic stroke.
We tested if the ε4 major isoform of the APOE gene and rs405509 and rs440446 promoter and intron-1 polymorphisms predicted risk of any dementia or Alzheimer's disease with diagnoses derived from the Hospital Discharge and Causes of Death Registers in 1453 participants of the Helsinki Birth Cohort Study.
In 630 cases and 595 controls, three APOE promoter SNPs -491A/T, -219G/T (rs405509), and +113G/C (rs440446) were genotyped and tested for association with type 2 diabetes in Hong Kong Chinese.
