Generation of two CASK patient-derived human induced pluripotent stem cell lines to study CASK-related disorders

First-of-their-kind patient stem cells now model a rare severe epilepsy syndrome, creating platforms to understand disease and test new drugs.

Two iPSC lines derived from CASK mutation patients were generated and validated, providing the first patient-specific human cellular models for CASK-related intellectual disability, a rare X-linked syndrome causing progressive microcephaly and severe epileptic encephalopathy. These iPSC resources enable mechanistic investigation of CASK function in human neurons and serve as platforms for drug screening in a disease with no approved disease-modifying therapies.

Why it surfaced

Patient-derived iPSC disease models for ultra-rare CASK-related disorder; enables mechanistic study and drug screening for a neurological rare disease with extreme unmet need and no current disease-modifying treatment.
