An important gene associated with Parkinson Disease 2, Autosomal Recessive Juvenile is PRKN (Parkin RBR E3 Ubiquitin Protein Ligase), and among its related pathways/superpathways are DNA Damage and Mitophagy. Affiliated tissues include brain and cortex, and related phenotypes are tremor and parkinsonism
