Deficiencies in CMA (caused by LRRK2 or VPS35 PD-associated mutations for example, Orenstein et al., 2013; Tang et al., 2015; Ho et al., 2016) cause accumulation of α-syn, favoring the emergence of aberrant α-syn species that hinder the function of the Lamp2A receptor. Here, LRRK2 is linked to Parkinson disease.
