PRKN, PINK1, and DJ-1 are related to mitochondrial function and mitophagy (183–185), as well as other genes linked to classical and atypical PD such as FBXO7, PLA2G6, VPS13C, and CHCHD2, which are involved in the mitochondrial quality control system (186). Here, CHCHD2 is linked to Parkinson disease.
