Quantitative assessment of the effect of FGF20 rs12720208 variant on the risk of Parkinson's disease: a meta-analysis.


OBJECTIVES Many studies have investigated the association between fibroblast growth factor 20(FGF20) rs12720208(C/T) polymorphism and the susceptibility of Parkinson's disease (PD). However, published data are still controversial. Here, we performed a meta-analysis to evaluate the association of rs12720208 polymorphism with the risk of PD. METHODS Up to April 2016, Pubmed, EMbase, Web of science, the Chinese National Knowledge Infrastructure, and Wanfang Medicine were reviewed to identify appropriate documents. A total of seven papers involving 11 studies with 3360 PD cases and 3681 controls were included based on the strict inclusion and exclusion standards. And STATA 12.0 statistics software was used to calculate available data from each study. The pooled odds ratios (OR) and 95% confidence interval (CI) were calculated to assess the association between FGF20 rs12720208 polymorphism and PD risk. RESULTS When all studies were pooled into this meta-analysis, neither the minor T allele frequencies nor the genotypic distributions were different between PD cases and controls. But the subgroup analysis stratified by ethnicity showed FGF20 rs12720208 polymorphism was associated with increased risk in the allele model (T vs. C:OR = 1.167, 95% CI = 1.020-1.335) and dominant model (TT + TC vs. CC:OR = 1.156, 95% CI = 1.001-1.335) in Caucasians but not in Asians. CONCLUSIONS This meta-analysis indicates that rs12720208 C/T variant might be associated with PD susceptibility in Caucasians.
