Significantly, approximately 10% of PD cases can be directly attributed to genetic factors, associated with mutations in genes including α‐synuclein (SNCA), E3 ubiquitin‐protein ligase parkin (PRKN), ubiquitin C‐terminal hydrolase L1 (UCHL1), PTEN‐induced putative kinase (PINK1), DJ‐1 (PARK7), leucine‐rich‐repeat kinase 2 (LRRK2), vacuolar protein sorting 35 homolog gene (VPS35), and β‐glucocerebrosidase 1 (GBA1), linked to autosomal dominant late‐onset. Here, PRKN is linked to Parkinson disease.
