Considering that there is overlap of the clinical manifestations and pathological characteristics between PD and MSA, we studied the possible associations between R1628P and G2385R polymorphisms of the LRRK2 and MSA in a population of Han Chinese patients.
The c.G4883C variant in the leucine-rich repeat kinase 2 (LRRK2) gene (protein effect: Arg1628Pro) has been recently proposed as a second risk factor for sporadic Parkinson's disease in the Han Chinese population (after the Gly2385Arg variant).
