A causal association has been established between autosomal recessive forms of PD and mutations affecting the mitophagy regulators PINK1 (PTEN‐induced putative kinase 1) and PRKN/PARK2 (Parkin RBR E3 ubiquitin protein ligase) (Kitada et al, 1998; Valente et al, 2004; Narendra et al, 2008; Matsuda et al, 2010). Here, PRKN is linked to Parkinson disease.
