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]. This evidence concerns the gene LRRK2 and Parkinson disease.
