ABSTRACT
We conducted this meta-analysis of relevant case-control studies to investigate the relationships between genetic polymorphisms in VDR, ESR1 and ESR2 genes to the susceptibility of Parkinson's disease (PD). A search on electronic databases without any language restrictions was conducted MEDLINE (1966-2013), the Cochrane Library Database (Issue 12, 2013), EMBASE (1980-2013), CINAHL (1982-2013), Web of Science (1945-2013) and the Chinese Biomedical Database (1982-2013). Meta-analysis was performed using the STATA statistical software. Crude odds ratio (OR) with their 95% confidence interval (95% CI) was calculated. Fourteen case-control studies with a total of 3,689 PD patients and 4,627 healthy subjects were included in our meta-analysis. The results of our meta-analysis demonstrated that the VDR genetic polymorphisms might be closely related to increased risks of PD (allele model OR = 1.18, 95% CI 1.09-1.29, P < 0.001; dominant model OR = 1.37, 95% CI 1.16-1.63, P < 0.001; respectively), especially for the polymorphisms rs7976091 and rs10735810. Our findings also illustrated that ESR1 genetic polymorphisms might increase the risk of PD (allele model OR = 1.56, 95% CI 1.17-2.07, P = 0.002; recessive model OR = 1.93, 95 % CI 1.33-2.80, P < 0.001; homozygous model OR = 1.35, 95% CI 1.02-1.79, P = 0.038; heterozygous model OR = 2.04, 95% CI 1.36-3.07, P = 0.001; respectively), especially for the polymorphisms rs2234693 and rs9340799. Furthermore, we found significant correlations of ESR2 genetic polymorphisms with the risk of PD (allele model OR = 1.78, 95% CI 1.19-2.67, P = 0.005; recessive model OR = 1.93, 95% CI 1.15-3.27, P = 0.014; homozygous model OR = 1.77, 95% CI 1.09-2.89, P = 0.022; heterozygous model OR = 1.88, 95% CI 1.08-3.27, P = 0.025; respectively), especially for the rs1256049 polymorphism. Our meta-analysis suggests that genetic polymorphisms in VDR, ESR1 and ESR2 genes may contribute to increased risks for PD.
