Abstract:
OBJECTIVE: We aimed to estimate the role of vacuolar protein sorting 13C (VPS13C) gene single nucleotide polymorphism (SNP) rs2414739 variant in the risk of PD by meta-analysis. METHODS: Five eligible case-control studies including 2796 PD cases and 4138 health controls involved in this meta-analysis. The fixed or random effect model was selected based on the heterogeneity of the included studies which detected by I² and Q tests. The association between rs2414739 polymorphism and the risk of PD was evaluated using the pooled odds ratios (OR) and 95 % confidence interval (95 %CI). Sensitivity analysis was used to test the stability of the results. Funnel plot and Begg's test were employed to verified publication bias. RESULTS: The results of our meta-analysis showed a significant correlation between VPS13C rs2424739 gene polymorphism and PD susceptibility in Allele model (A versus vs. G: OR = 1.14, 95 %CI = 1.05-1.23, p = 0.002), dominant model (GG + AG vs. AA: OR = 0.86, 95 %CI = 0.78-0.95, p = 0.004), heterozygote model (AG vs. AA: OR = 0.87, 95 %CI = 0.77-0.99, p = 0.04), homozygote model (GG vs. AA: OR = 0.76, 95 %CI = 0.60-0.96, p = 0.02). Surprisingly, we did not find a significant statistical difference between VPS13C rs2414739 polymorphism and PD risk in Chinese cohort in the regional stratified analysis. CONCLUSIONS: This meta-analysis suggests that VPS13C rs2414739 polymorphism might act as a genetic predisposition factor for PD, whereas does not include Chinese population.
