PRKN and Parkinson disease: A compelling link between glial physiopathology and PD genes has been the identification of a panel of mutated genes, including α‐synuclein (SNCA), parkin (PRKN), PINK1, PTEN‐induced putative kinase (DJ1), and leucine‐rich repeat kinase 2 (LRRK2) in astrocytes and/or microglial cells (Ashley et al., 2016; Barodia et al., 2019; Booth et al., 2017; Choi et al., 2016; Dzamko et al., 2015).
