AB126. Association between FOX03A gene polymorphisms and human longevity: a meta-analysis

ABSTRACT:

Objective

Numerous studies have shown associations between the FOX03A gene, encoding the forkhead box 03 transcription factor, and human or specifically male longevity. However, the associations of specific FOX03A polymorphisms with longevity remain inconclusive. We performed a meta-analysis of existing studies to clarify these potential associations.

Methods

A comprehensive search was conducted to identify studies of FOX03A gene polymorphisms and longevity. Pooled odds ratios (ORs) and 95% confidence intervals (Cls) were calculated by comparing the minor and major alleles.

Results

A total of seven articles reporting associations of FOX03A polymorphisms with longevity were identified and included in this meta-analysis. These comprised 11 independent studies with 5241 cases and 5724 controls from different ethnic groups. rs2802292, rs2764264, rsI3217795, rs1935949 and rs2802288 polymorphisms were associated with human longevity (OR =1.36, 95% CI, 1. 10–1.69, P=0.005; OR =1.20, 95% CI, 1.04–1.37, P=0.01; OR =1.27, 95% CI, 1.10–1.46, P=0.001; OR =1.14, 95% CI, 1.01–1.27 and OR =1.24, 95% CI, 1.07–1.43, P=0.003, respectively). Analysis is stratified by gender indicated significant associations between rs2802292, rs2764264 and rs13217795 and male longevity (OR =1.54, 95% CI, 1.33–1.79, P<0.001; OR =1.38, 95% CI, 1.15–1.66, P=0.001; and OR =1.39, 95% CI, 1.15–1.67, P=0.001), but rs2802292, rs2764264 and rs1935949 were not linked to female longevity. Moreover, our study showed no association between rs2153960, rs7762395 or rs13220810 polymorphisms and longevity.

Conclusions

In conclusion, this meta-analysis indicates a significant association of five FOX03A gene polymorphisms with longevity, with the effects of rs2802292 and rs2764264 being male-specific. Further investigations are required to confirm these findings.
