abstract：:Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are the most common cause of familial Parkinson's disease (PD) with autosomal dominant inheritance. Accordingly, LRRK2 has emerged as a promising therapeutic target for disease modification in PD. Since the first discovery of LRRK2 mutations some 12 years ago,...
