Establishment of a human induced pluripotent stem cell (iPSC) line (HIHDNEi002-A) from a patient with developmental and epileptic encephalopathy carrying a KCNA2 (p.Arg297Gln) mutation

Abstract

Developmental and epileptic encephalopathies (DEE) can be caused by mutations in the KCNA2 gene, coding for the voltage-gated K+ channel Kv1.2. This ion channel belongs to the delayed rectifier class of potassium channels and plays a role during the repolarization phase of an action potential. In this study we reprogrammed fibroblasts from a 30-year-old male patient with DDE carrying a point mutation (c.890G > A, p.Arg297Gln) in KCNA2 to induced pluripotent stem cells. Pluripotency state of the cells was verified by the capability to differentiate into all three germ layers and the expression of several pluripotency markers on RNA and protein levels.
