TARDBP and amyotrophic lateral sclerosis: The first ALS‐related gene, encoding a cytosolic Cu/Zn‐binding SOD (SOD1) was reported in 1993 (Dal Canto & Gurney, 1994; Ripps et al., 1995; Rosen et al., 1993) and since 2011, mutations in more than 20 genes have been identified (e.g. C9orf72, TARDBP, FUS, HNRNPA1, SQSTM1, VCP, OPTN and PFN1).
