Read our Parkinson Disease research guide →Researchers are building a database of people with Parkinson's disease who have specific variants in a gene called SNCA. By collecting blood samples and measuring how the disease affects different people, the study aims to better understand how these genetic changes influence Parkinson's symptoms and progression in mainland China.
Certain variations in the SNCA gene are known to increase the risk of Parkinson's disease, but doctors don't yet fully understand how these genetic differences affect individual patients' symptoms and disease course. This registry will help researchers learn more about the link between these genetic variants and real-world disease patterns.

You would visit the research center to have your blood drawn and to complete a series of clinical assessments and questionnaires about your Parkinson's symptoms—including how the disease affects your movement, sleep, mood, and daily life. The study also measures biomarkers in your blood. Your information will be added to a registry that researchers will use to study patterns in how the disease develops in people with these genetic variants.
