      Disease: probable diagnosis.

    2. Willingness to undergo genetic testing, and choose to be informed of genetic testing results for GBA, LRRK2 and 5 additional PD related genes (SNCA, VPS35, PRKN, PINK-1, PARK7).
    3. Capacity to give full informed consent in writing or electronically, and have read and signed the informed consent forms (ICFs) based on site clinician's determination.

      Study Population 2: People at risk of developing PD (not open for recruitment)

      1. Family members of Study Population 1 may be invited to participate in the study if confirmatory genetic testing is deemed necessary by the genetic testing laboratory.

You CAN'T join if...
