Hereditary transthyretin amyloidosis (ATTR) is an autosomal dominant rare disease caused by heterozygous mutations in the TTR gene, which encodes depolymerized transthyretin deposited in several organs. An induced pluripotent stem cell (iPSC) line of ATTR was generated from peripheral blood mononuclear cells of a 28 years old male patient carrying the TTR mutation p.Phe53Val. We used non-integrated episomal vectors to achieve the reprogramming of PBMCs, and further proved pluripotency by expression of typical stemness surface markers, gene expression of pluripotency genes and the pathological evidence of teratoma forming three germ layers in vivo. This iPSC line is a useful cellular model for screening potential therapeutic targets and studying the pathogenic mechanism of disease.
