Generation of three human induced pluripotent stem cell (iPSC) lines from three patients with Dravet syndrome carrying distinct SCN1A gene mutations

摘要

Dravet syndrome (DS) is a childhood epilepsy syndrome caused by heterozygous mutations in the SCN1A gene encoding voltage-gated sodium channel Nav1.1. We generated iPSCs from fibroblasts of three DS patients carrying distinct SCN1A mutations (c.5502-5509dupGCTTGAAC, c.2965GC and c.651CG). The iPSC lines were genetically stable and each line retained the SCN1A gene mutation of the donor fibroblasts. Characterization of the iPSC lines confirmed expression of pluripotency markers, absence of exogenous vector expression and trilineage differentiation potential. These iPSC lines offer a useful resource to investigate the molecular mechanisms underlying Nav1.1 haploinsufficiency and for drug development to improve treatment of DS patients.
