Genetic testing for Parkinson’s risks can be useful to people with and without the disease. It can also help advance research into the complex condition. Although the testing usually occurs in a research setting, it can also happen through a movement disorder specialist or online screenings. Genetic testing currently has no direct impact on clinical care, but it can determine whether someone is at risk to develop the disease. Genetic testing also helps identify potential candidates for important research trials. In all cases, genetic counsellors can help patients understand the testing, interpret results, and establish future actions.
