Despite most cases of PD resulting from sporadic mutations, inherited PD remains a legitimate concern and is highly correlated with many genes, including Synuclein alpha (SNCA), Leucine-rich Repeat Kinase 2 (LRRK2), Parkin (PRKN), PTEN Induced Kinase 1 (PINK1), VPS35 Retromer Complex Component (VPS35), and Vacuolar Protein Sorting 13 Homolog C (VPS13C) [137]. Here, SNCA is linked to Parkinson disease.
