Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by the progressive death of dopaminergic neurons present in the substantia nigra. The clinical presentation of PD includes tremors, slowed movement (bradykinesia), muscle and limb rigidity, and difficulty with walking and balancing. While many environmental factors can affect the onset and progression of the disease, genetic mutations have a large influence. Of the identified PD-linked genetic mutations, mutations in the leucine-rich repeat kinase 2 (LRRK2) are one of the most common genetic causes of PD. Located in endosomes, LRRK2 has been shown to play a role in the sorting and endocytosis …
