LRRK2 and Parkinson disease: Several other genes have been clinically associated with the autosomal dominant inheritance pattern of PD—UCHL1 (ubiquitin C-terminal hydrolase 1; PARK5), LRRK2 (leucine-rich repeat kinase 2; PARK8), GIGYF2 (GRB10 interacting GYF protein 2; PARK11), VPS35 (vacuolar protein sorting 35; PARK17) [60,61,62], and GBA1 (glucocerebrosidase 1).
