Hereditary Parkinson's disease accounts for approximately 10-15% of all Parkinson's cases. The majority of Parkinson's disease cases are sporadic, meaning they occur without a clear genetic link. Genetic mutations, such as those in the SNCA, LRRK2, and PARK7 genes, are associated with the hereditary form of the disease. Overall, while genetics play a role, most individuals with Parkinson's do not have a family history of the disorder.
