De novo mutations in SCN1A are the most common cause of Dravet syndrome (DS), an infantile-onset epileptic encephalopathy. In this study, human induced pluripotent stem cell (hiPSC) line FUi002-A was generated from skin fibroblasts obtained from a clinically diagnosed 26-year-old male DS patient with the R1525X variant of the SCN1A gene. Skin fibroblasts were reprogrammed using OriP/EBNA-1 based episomal plasmids expressing reprogramming factors expressing OCT4, SOX2, KLF-4, L-MYC, LIN28, and p53 shRNA. The transgene-free FUi002-A showed pluripotency, three germ layer differentiation capacity in vitro, and a normal karyotype. The resulting hiPSCs were heterozygous for the mutation in the SCN1A gene.
