The single nucleotide polymorphism Rs12817488 is associated with Parkinson's disease in the Chinese population.

A recent meta-analysis of datasets from five of the published Parkinson's disease (PD) genome-wide association studies implicated the single nucleotide polymorphism (SNP) rs12817488 in coiled-coil domain containing 62 (CCDC62)/huntingtin interacting protein 1 related (HIP1R) as a risk factor for PD. We conducted a case-control study to evaluate the possible association between rs12817488 and PD in Chinese people. All patients (515 PD patients and 518 age and sex-matched controls) were successfully genotyped using polymerase chain reaction restriction fragment length polymorphism analysis. We observed that the rs12817488 polymorphism is associated with PD (p=0.003) and that the genotype and allele frequencies showed a difference between late-onset PD patients and male controls (p=0.025 and p=0.007, respectively). However, there was no difference in the early-onset PD patients and controls. We found a difference in the genotype and allele frequencies between the male PD patients and the male controls (p=0.034 and p=0.017, respectively). However, there was no difference in females. Patients with the A allele were susceptible to PD in both dominant (GA+AA versus GG; odds ratio [OR] 1.365, 95% confidence interval [CI] 1.041-1.788) and recessive (AA versus GG+GA; OR 1.606, 95% CI 1.194-2.158) models. Therefore, our findings support the conclusion that the rs12817488 in CCDC62/HIP1R polymorphism may increase the risk of PD in the Chinese Han population.
