Generation of D1-1 TALEN isogenic control cell line from Dravet syndrome patient iPSCs using TALEN-mediated editing of the SCN1A gene

Stem Cell Res. 2018 Apr;28:100-104. doi: 10.1016/j.scr.2018.01.036. Epub 2018 Feb 2.


Dravet syndrome (DS) is an infantile epileptic encephalopathy mainly caused by de novo mutations in the SCN1A gene encoding the α1 subunit of the voltage-gated sodium channel Nav1.1. As an in vitro model of this disease, we previously generated an induced pluripotent stem cell (iPSC) line from a patient with DS carrying a c.4933C>T (p.R1645*) substitution in SCN1A. Here, we describe developing a genome-edited control cell line from this DS iPSC line by substituting the point mutation with the wild-type residue. This artificial control iPSC line will be a powerful tool for research into the pathology of DS.
