TARDBP and amyotrophic lateral sclerosis: We generated iPSCs from nine fibroblasts of patients with ALS carrying SOD1 (SOD1-1, SOD1-2, SOD1-3, and SOD1-4), TARDBP (TARDBP-1 and TARDBP-2), FUS (FUS-1 and FUS-2), or C9orf72 gene mutations, and four fibroblasts from healthy individuals (Figures S1A–S1C; Table S1).
