In contrast, other studies reported decreased mitophagy in G2019S-LRRK2 PD and PRKN-PD–derived fibroblasts [113], in G2019S-LRRK2 PD–derived neural stem cells [103], and in starved PD–derived dermal fibroblasts from DJ1 mutation carriers [114]. The gene discussed is PARK7; the disease is Parkinson disease.
