Generation of iPSC lines (KAUSTi011-A, KAUSTi011-B) from a Saudi patient with epileptic encephalopathy carrying homozygous mutation in the GLP1R gene.

Glucagon-like peptide-1 receptor (GLP1R) is a seven-transmembrane-spanning helices membrane protein expressed in multiple human tissues including pancreatic islets, lung, brain, heart and central nervous system (CNS). GLP1R agonists are commonly used as antidiabetic drugs, but a neuroprotective function in neurodegenerative disorders is emerging. Here, we established two iPSC lines from a patient harboring a rare homozygous splice site variant in GLP1R (NM_002062.3; c.402 + 3delG). This patient displays severe developmental delay and epileptic encephalopathy. Therefore, the derivation of these iPSC lines constitutes a primary model to study the molecular pathology of GLP1R dysfunction and develop novel therapeutic targets.
