Epilepsy of infancy with migrating focal seizures (EIMFS) is a kind of epileptic encephalopathy with high genetic heterogeneity. The most common pathogenic gene for EIMFS is potassium sodium-activated channel subfamily T member 1 (KCNT1). Using Sendai virus-mediated reprogramming, we established an induced pluripotent stem cell (iPSC) line from the peripheral blood mononuclear cells (PBMCs) of a five-month-old Chinese girl with heterozygous missense mutation (c.2800 G>A) in the KCNT1 gene. The iPSCs were stable during amplification, expressed pluripotent genes, maintained a normal karyotype, and showed characteristics of the three germs layers in an in vitro differentiation assay.
婴儿癫痫伴游走性局灶性发作（EIMFS）是一种具有高度遗传异质性的癫痫性脑病。EIMFS 最常见的致病基因是钾钠离子激活通道亚家族 T 成员 1（KCNT1）。我们利用仙台病毒介导的重编程，从一位五个月大的中国女孩外周血单核细胞（PBMCs）中建立了一个诱导多能干细胞（iPSC）系，该女孩的 KCNT1 基因存在杂合错义突变（c.2800 G>A）。在扩增过程中，iPSCs 稳定，表达多能基因，保持正常核型，并在体外分化试验中表现出三个胚层的特征。
