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. This evidence concerns the gene PARK7 and Parkinson disease.
