Association of GAK rs1564282 With Susceptibility to Parkinson's Disease in Chinese Populations.

ABSTRACT: The susceptibility of the GAK rs1564282 variant in Parkinson's disease (PD) in Europeans was identified using a series of published genome-wide association studies. Recently, some studies focused on the association between rs1564282 and PD risk in Chinese populations but with inconsistent results. Thus, we conducted an updated meta-analysis with a total of 7,881 samples (4,055 PD cases and 3,826 controls) from eligible studies. After excluding significant heterogeneity, we showed that the rs1564282 variant was significantly associated with PD in Chinese populations (p = 1.00E-04, odds ratio = 1.28 and 95% confidence interval = 1.16-1.42). The sensitivity analysis showed that the association between rs1564282 and PD was not greatly influenced, and there was no significant publication bias among the included studies. Consequently, this meta-analysis indicates that the GAK rs1564282 variant is significantly associated with susceptibility to PD in Chinese populations.

Project description:BACKGROUND: The cause of almost all cases of Parkinson's disease (PD) remains unknown. Recent years have seen an explosion in the rate of discovery of genetic defects linked to PD. Different racial and geographical populations may have different distributions of genetic variants. METHODS: In the current study, we screened the following genetic variants, including some rare mutations and single nucleotide polymorphisms (SNPs), in a pedigree and cases-controls. To best of our knowledge, we first screened these variants known to be associated with neurodegeneration disease, E46K (rs104893875) in SNCA, A1442P in LRRK2, IVS9 in PARK2, A350V in SLC41A1, P268S (rs2066842), R702W (rs2066844), G908R (rs2066845), 1007fs (rs2066847) in NOD2 and G2385R (rs34778348) in LRRK2 from southern China population. Genotyping was performed by jointly using primers overlapping polymerase chain reaction (PCR) site-directed mutagenesis, restriction fragment length polymorphism (RFLP), and capillary electrophoresis (CE). RESULTS: We didn't discover above 9 variants in the family members of the pedigree. Furthermore, of 237 patients with sporadic Parkinson's disease and 190 controls, no heterozygosity or homozygosity were found from E46K, A1442P, A350V, R702W, G908R, or 1007fs but heterozygosity onto G2385R, IVS9, and P268S. No significant difference between cases and controls was found in both allele frequency (P = 0.572) and genotype frequency (P = 0.348) of IVS9. However, significant differences in genotype frequency (P = 0.009) of G2385R were consistent with prior observation. Eight patients with Parkinson's disease (2 women and 6 men are over the age of 50 years at onset of PD) carried the P268S heterozygous variation in NOD2. There was no heterozygosity or homozygosity of P268S in the controls. Genotype frequency of P268S (P = 0.0450) had significant differences. CONCLUSIONS: Our results suggested that the P268S variant in NOD2 might be a risk factor for susceptibility to sporadic Parkinson's disease in Chinese populations. It also implied that the inflammatory response may play a role in PD.
