The rs3129882/rs4248166 in HLA-DRA and rs34372695 in SYT11 are not associated with sporadic Parkinson’s disease in Central Chinese population

Abstract

Background

Parkinson’s disease (PD) is a common progressive neurodegenerative disorder. Up to now, several single-nucleotide polymorphisms (SNPs) located in virulence gene sites have been reported linked to PD. Candidate gene association studies and genome-wide association studies have identified rs3129882, rs4248166 in HLA-DRA and rs34372695 in SYT11 as risk factors for familial or sporadic PD. However, the association between variants of HLA-DRA, SYT11 and PD are still controversial, especially in the Central Chinese population. We here performed a case-control study to investigate whether HLA-DRA and SYT11 genes could predispose to sporadic PD in the Chinese population.

Methods

We investigate 486 PD patients and 457 age- and sex-matched controls from Central China to assess this association.

Results

In the allele model, the odds ratio (OR) result of rs3129882 was 0.905 (p = 0.287). Moreover, no significant difference was observed in the association between rs424816 (OR = 0.864, p = 0.106) and rs34372695 (p = 1.0) with PD risk. Genotypic analysis in SNP rs3129882, rs4248166 and rs34372695 indicated no significant association with PD. Subgroup analysis of our data showed age-onset and gender were not associated with either genotype or minor allele frequencies of rs3129882 and rs4248166. Moreover, the negative results were also observed in a meta-analysis of studies of rs3129882 from mainland China and Taiwanese population.

Conclusions

Our results reveal that rs3129882, rs4248166 and rs34372695 do not confer significant risks for sporadic PD in the Central Chinese population.
