Generation of an induced pluripotent stem cell line from a patient with epileptic encephalopathy caused by the CYFIP2...

Induced pluripotent stem cells (iPSCs) opened the possibility to use patient cells as a model for several diseases. iPSCs can be reprogrammed from somatic cells collected in a non-invasive way, and then differentiated into any other cell type, while maintaining the donor´s genetic background. CYFIP2 variants were associated with the onset of an early form of epileptic encephalopathy. Studies with patients showed that the R87C variant seems to be one of the variants that causes more severe disease, however, to date there are no studies with a human cell model that allows investigation of the neuronal phenotype of the R87C variant. Here, we generated an iPSC line from a patient with epileptic encephalopathy caused by the CYFIP2 R87C variant. We obtained iPSC clones by reprogramming urinary progenitor cells from a female patient. The generated iPSC line presented a pluripotent stem cell morphology, normal karyotype, expressed pluripotency markers and could be differentiated into the three germ layers. In further studies, this cell line could be used as model for epileptic encephalopathy disease and drug screening studies.
