About

The purpose of the Chinese PD-SNCA Registry(CPD-SNCAR) is to develop a database of patients of Parkinson's disease with a-synuclein (SNCA) gene variants in mainland China.

Full description

Parkinson's disease (PD) is the second most common disorder among neurodegenerative diseases. SNCA is the first gene implicated in monogenic parkinsonism. However, some polymorphisms of SNCA gene such as rs894278 and rs11931074 can affect the risk of sporadic PD. The investigators aim to establish a database of PD with SNCA variants and characterize the clinical manifestation of these patients in mainland China.

Method:

Peripheral blood from patients has been tested to have SNCA gene variants. Clinical manifestation will be measured by scales and neurological tests. Standard scales include: Unified Parkinson's Disease Rating Scale(UPDRS), Hoehn-Yahr stages, Non-Motor Symptoms Scale (NMSS), mini-mental state examination (MMSE), Parkinson disease sleep scales (PDSS), Rapid Eye Movement Sleep Behaviour Disorder Questionnaire(RBDQ-HK), Epworth Sleepiness Scale (ESS), Rome III functional constipation scale, the Scale for Outcomes in PD for Autonomic Symptoms (SCOPA-AUT), Parkinson Fatigue Scale (PFS), Cambridge-Hopkins Restless Legs Syndrome questionnaire (CHRLSq), Hyposmia rating scale(HRS), Hamilton depression scale, the 39-item Parkinson's Disease Questionnaire(PDQ-39), Freezing of gait scale(FOG), dyskinesia related scales, Wearing-off scale(WO). The investigators will also exam the blood biomarkers of PD such as uric acid and peripheral inflammatory markers.

Enrollment: 3,000 estimated patients

Sex: All

Volunteers: No Healthy Volunteers
