VPS35 and Parkinson disease: The steady-state levels of VPS35 are not significantly different in caudate putamen extracts from a series of control and idiopathic PD/DLB subjects (Fig. 1F, refer to Table 1) or in frontal cortex extracts from an independent series of control, idiopathic PD or G2019S LRRK2-linked PD subjects (Fig. 1G, refer to Table 2).
