title: The contribution of GIGYF2 to Parkinson's disease: a meta-analysis.
abstract: The contribution of the gene of GIGYF2, Grb10-Interacting GYF Protein 2, to Parkinson's disease (PD) is still ambiguous. To explore the contribution of GIGYF2 to PD at the genetic level, we analyzed the relationship between all reported GIGYF2 variants (including mutations and polymorphisms) and PD through a meta-analysis. Databases including Medline, Embase, etc., were searched to find relevant studies. All eligible publications have to meet the strict inclusion and exclusion criteria listed. Two authors independently selected trials, assessed the article's quality and extracted data. Odds ratios (ORs) and relative risks with 95 % confidence intervals (CIs) were used to evaluate the strength of associations. All analyses were carried out by using the Review Manager software package v.5.2. More than 100 variants of GIGYF2 were reported either or both in patients and controls in 10 included publications. The 10 publications totally included 5466 patients and 6517 controls. We conducted meta-analyses for the following variants: N56S, N457T, Del LPQQQQQQ 1209-1216, Del Q 1210 (rs10555297), rs12328151, rs2289912, rs2305138, rs3816334, A572A and H1171R. The ORs for N56S were 2.86 (95 % CI 1.10, 7.41) for PD and 4.75 (95 % CI 1.35, 16.68) for FPD. And the OR for N457T in FPD was 4.53 (95 % CI 1.04, 19.66). On the other hand, other variants involved in meta-analyses were not related to PD. This research results suggest that the N56S and N457T of GIGYF2 are risk factors for PD in Caucasians, but not in Asians.
