Mitochondrial homeostasis is connected to the majority of genes linked to PD, including SNCA (PARK1/4), PRKN (PARK2), PINK1 (PARK6), DJ-1 (PARK7), LRRK2 (PARK8), ATP13A2 (PARK9), PLA2G6 (PARK14), FBXO7, VPS35, CHCHD2, and VPS13C (Monzio Compagnoni et al., 2020; Toffoli et al., 2020). The gene discussed is SNCA; the disease is Parkinson disease.
