Over 30 genes have been linked to ALS thus far [7], with the most prevalent ALS-associated mutations being located in C9ORF72 (chromosome 9 open reading frame 72), SOD1 (Cu/Zn superoxide dismutase 1), TARDBP (TAR DNA-binding protein 43; TDP-43), and FUS (fused in sarcoma) [8]. Here, SOD1 is linked to amyotrophic lateral sclerosis.
