SOD1 and amyotrophic lateral sclerosis: From the original ALS mouse model representing the familiar form of ALS with the mutation of the superoxide dismutase 1 (G93A‐SOD1) gene,5 a growing number of rodent models that express different mutations, such as the fused in sarcoma (FUS),6 the C9orf72 hexanucleotide repeat expansion mice,7, 8 and the transactive response DNA binding protein 43 kDa TDP‐439, 10 (among others) have been increasingly developed to address the effects of molecular changes on neuronal degeneration and death.
