Background: A new SNCA mutation, H50Q, has been linked to familial Parkinson disease (PD). Results: The H50Q mutation does not affect the structure, membrane binding, or subcellular localization of α-Syn but alters its pathogenic properties. Conclusion: The H50Q mutation increases α-Syn aggregation, secretion, and extracellular toxicity. Significance: α-Syn mutations contribute to the pathogenesis of PD via multiple mechanisms.
