“…This may be particularly relevant for families with sporadic cases of C9orf72 ALS/FTD. Ectopic cytoplasmic localization of mutant TDP43, FUS and MATR3 or overexpression of wildtype TDP43, FUS and MATR3 protein has been shown to be associated with ALS phenotypes in patients and model systems, respectively (Lagier-Tourenne, Polymenidou et al, 2010, Malik, Miguez et al, 2018, Mitchell, McGoldrick et al, 2013, Tada, Doi et al, 2018, Wils, Kleinberger et al, 2010. C9orf72, a DENN (differentially expressed in normal and neoplastic cells) domain containing protein, has been shown to play a role in autophagy and immune-regulatory functions (Lall & Baloh, 2017, Levine, Daniels et al, 2013, Nassif, Woehlbier et al, 2017.…”
