Association between HLA rs3129882 polymorphism and Parkinson's disease: a meta-analysis.

Abstract

OBJECTIVE:

As one of potential candidate genes for the risk of Parkinson's disease (PD), the HLA-DRA/PARK18 (rs3129882, A > G) gene has been studied extensively. However, direct evidence for the genetic association studies between PD and rs3129882 remains inconclusive. The aim of our meta-analysis was to determine a more reliable association between the rs3129882 and PD.

MATERIALS AND METHODS:

Comprehensive search strategy was used for electronic searches through PubMed, Elsevier, Springer Link, CNKI (Chinese National Knowledge Infrastructure) and WanFang (Chinese) databases to evaluate the association between rs3129882 and PD risk. Data were extracted and the odd ratios (ORs) and 95% confidence intervals (95% CIs) were calculated. Finally, we performed a meta-analysis of 13 appropriate papers by using a total of 11951 patients and 11902 controls.

RESULTS:

The meta-analysis showed no significant association between rs3129882 and PD risk in all four models (the allele model, dominant model, homozygote model and the recessive model). In allele model, the result was OR = 1.043 (95% CI = 0.978, 1.113). Moreover, this association remained no significant in the subgroup analysis stratified by ethnicity.

CONCLUSIONS:

In current meta-analysis, no significant association was found for rs3129882 and PD risk. And more well-designed primary researches will be needed to further evaluate the interaction of rs3129882 polymorphism and the susceptibility of PD.
