Rs2802292

From SNPedia

A study of 5 genes in 3,741 Japanese men, some of whom lived significantly longer than average (centarians), concluded that the FOXO3 gene (also known as FOXO3A) harbors several SNPs linked to longevity, including this SNP, rs2802292, as well as rs2764264 and rs13217795.

The odds ratio for rs2802292(G;G) vs (T;T) carriers was 2.75 (p = 0.00009; adjusted p = 0.00135). It is not known yet if this correlation is specific to Japanese males.[PMID 18765803]

This is discussed extensively at geneticfuture as a longevity snp.

• (T) shorter lifespan
• (G) longer lifespan

Quoted from the geneticfuture article: "No-one should consider this association to be definitive until it's been replicated in independent cohorts. Secondly, the effects of this variant are likely to differ between groups. According to the HapMap database the frequency of the "die early" (T) version of the variant varies substantially between populations: it's around 76% in Japanese, slightly more common (81%) in Chinese, less common (58%) in Europeans, and quite rare (17%) in West Africans. Given that the Japanese have the highest life expectancy of any of these populations, this is a counter-intuitive result, which reinforces the fact that there are many genes and other factors influencing variation in longevity."

spittoon longevity rs2802288(A) increased the odds of living to 100 by 1.5x. rs2802288 is located very close to rs2802292 which was previously reported to have a similar effect.

A study of males from the Southern Italian Centenarian Study also replicated the association between rs2802288, a proxy of rs2802292, and longevity, with an odds ratio of 1.51 (CI: 1.15-1.98, p = 0.003).[PMID 19415983]
