Rapid screening of ATP13A2 variant with high-resolution melting analysis.
Several genetic and environmental factors are involved in the pathogenesis of Parkinson's disease (PD). Recently, a novel variant of ATP13A2 (p.A746T) responsible for PARK9 was reported as a risk factor for PD in the Han-Chinese population. To investigate the role of this variant in Japanese PD patients, we examined 917 Japanese PD patients (871 index cases) and 190 controls by high-resolution melting curve analysis. We detected heterozygous p.A746T variant in a single patient with sporadic PD and a single control subject. These results suggest that ATP13A2 p.A746T variant is unlikely to play a role as a common risk factor or a pathogenic mutation for PD at least in Japanese. Our data on Japanese differ from those reported recently on Han-Chinese. Further studies are needed to confirm conclusions on roles of ATP13A2 variant in Asians or other populations.
