Clinical feature will be measured by scales and neurological tests.Standard scales includes: Unified Parkinson's Disease Rating Scale(UPDRS), Hoehn-Yahr stages, NMSS, MMSE, PDSS(Parkinson disease sleep scales),Rapid Eye Movement Sleep Behaviour Disorder Questionnaire(RBDQ-HK),ESS(Epworth Sleepiness Scale),Rome III functional constipation scale,SCOPA-AUT (the Scale for Outcomes in PD for Autonomic Symptoms),PFS(Parkinson Fatigue Scale),CH-RLSq,Hyposmia rating scale(HRS)HAMILT depression scale,the 39-item Parkinson's Disease Questionnaire(PDQ-39),Freezing of gait scale(FOG),dyskinesia related scales, Wearing-off scale(WO)\n2. Peripheral blood from patients was collected for whole exome sequencing.\n3.
