wy body pathology. The researchers found that LRRK2 can interfere with CMA in neurons and that this interference appears to cause α-synuclein accumulation. This mechanism may underlie the α-synuclein pathology in LRRK2 PD cases.

Background/Significance: The phenotype of Parkinson's disease (PD) patients with LRRK2 mutations is often similar to that of non-carriers. The purpose of this study was to compare PD phenotype of LRRK2 carriers and non-carriers in a large Ashkenazi Jewish PD cohort. The researchers found that LRRK2 PD in Ashkenazi Jews is characterized by earlier age-at-onset, frequent lower extremity involvement at onset, persistent response to levodopa, and dyskinesia.
