Generation and characterization of two human iPSC lines from patients with methylmalonic acidemia cblB type

Abstract Two human induced pluripotent stem cell (iPSC) lines were generated from fibroblasts of two siblings with methylmalonic acidemia cblB type carrying mutations in the MMAB gene: c.287T➔C (p.Ile96Thr) and a splicing loss-of-function variant c.584G➔A affecting the last nucleotide of exon 7 in MMAB (p.Ser174Cysfs*23). Reprogramming factors OCT3/4 , SOX2 , KLF4 and c-MYC were delivered using a non-integrative method based on the Sendai virus. Once established, iPSCs have shown full pluripotency, differentiation capacity and genetic stability.
