MFF and neurodegenerative disease: Moreover, loss‐of‐function variants in DNM1L or genes involved in DRP1‐dependent fission including MIEF1 (Charif et al,2021), SLC25A46 (Abrams et al,2015, 46), MFF (Koch et al,2016), GDAP1 (Baxter et al,2002), and INF2 (Boyer et al,2011) all‐cause severe neurodegenerative diseases, making them unlikely therapeutic targets.
