HLA rs3129882 variant in Chinese Han patients with late-onset sporadic Parkinson disease

Recently, the rs3129882 variant in intron 1 of HLA-DRA was found to be associated with late-onset sporadic Parkinson disease (PD) in Americans of European ancestry. To evaluate whether the same variant is related to PD in Chinese population, we investigated late-onset sporadic PD patients of Chinese Han ethanicity in Mainland China. We found significant difference in genotypic and allele distribution between patients and control subjects (chi(2)=6.446, p=0.040 for genotypic distribution; chi(2)=5.762, p=0.016 for allele distribution), suggesting this variant is associated with late-onset sporadic PD in Chinese Han population.
