The clinical manifestations of LRRK2-related PD have been described as being more benign than those shown in idiopathic PD, where motor symptoms (disease severity, rate of progression, occurrence of falls, and dyskinesia) and non-motor symptoms (cognition and olfaction) are less severe (17), whereas familial PD caused by LRRK2 have been described as being similar to idiopathic PD (18). The gene discussed is LRRK2; the disease is Dyskinesia.
