In neurodegenerative diseases, notably, frontotemporal dementia (FTD) and Parkinson’s disease (PD), genetic mutations—including MAPT, LRRK2, PINK1, PRKN, and SNCA—have been reported to alter Nrf2 signaling, both in vitro and in vivo. This evidence concerns the gene NFE2L2 and neurodegenerative disease.
