SOD1 and amyotrophic lateral sclerosis: The differentiation of iPSC-derived MNs of three different cell lines from healthy subjects and two ALS patient cell lines carrying SOD1 (homozygous D90A mutation [one clone], heterozygous R115G mutation [one clone]) and TARDBP (both heterozygous S393L, G294V [two clones from patient]) mutations as well as the NGS-RNAseq had already been established previously (Dash et al., 2024).
