goodMag 5.5This is a intron variant variant in the FOXO3 gene.
Key Literature Trait Associations
Longevity
rs2802292 in FOXO3 is one of the most replicated longevity-associated variants across multiple ethnic groups including Japanese, German, Chinese, Italian, and American cohorts. The T allele increases FOXO3 transcription, enhancing cellular stress resistance, DNA repair, autophagy, and apoptosis of damaged cells. FOXO3 is a master regulator of the insulin/IGF-1 signalling pathway, and its activation mimics some effects of caloric restriction.
Coronary heart disease mortality
The FOXO3 rs2802292 G allele is associated with a 26% reduction in coronary heart disease (CHD) mortality in older men. In a prospective cohort of 3,584 Japanese-American men followed for 17 years (Honolulu Heart Program), plus a replication cohort of 2,651 white and Black elderly individuals (Health ABC), G allele carriers showed HR=0.74 (95% CI 0.64–0.86, p=0.00004) for CHD death and HR=0.90 (95% CI 0.84–0.95, p=0.001) for total mortality. No significant associations were detected for cancer or stroke mortality, suggesting the longevity benefit is partly mediated through cardiovascular pathways.
Essential hypertension
The rs2802292 G allele is associated with lower blood pressure and reduced essential hypertension risk, primarily in women of Japanese ancestry. In a meta-analysis with Japanese replication cohorts, women homozygous for the G allele had ~6 mmHg lower systolic and ~3 mmHg lower diastolic blood pressure, with minor allele homozygote frequency of 9.5% in normotensive vs. 3.3% in hypertensive women (p=0.03–0.04). A separate 2024 study found that the G allele mitigates the cerebral microinfarct risk associated with hypertension. Effects were not significant in men, and diverged across populations (European ancestry showed an opposite trend).
Type 2 diabetes mellitus
The rs2802292 G allele is associated with lower fasting blood glucose levels in elderly Chinese women, though not with type 2 diabetes (T2D) risk per se. In a case-control study of 843 elderly Chinese adults (426 T2D, 417 controls), G-allele carriers showed reductions of 0.75–1.15 mmol/L in fasting glucose compared to TT homozygotes in women (p=0.001–0.03), with no comparable effect in men. Separately, a Southern Chinese longevity study found GG homozygotes had improved HOMA-IR (p=0.014), suggesting the G allele may confer metabolic benefits through improved insulin sensitivity, consistent with FOXO3's role in the insulin/IGF-1 pathway.
