The investigators will obtain medical history, family history, MRI records, patient photographs, genetic test results, neurobehavioral and quality of life questionnaires from individuals with confirmed or suspected CAGS at annual research visits. Participants may also complete standardized research neurobehavioral assessments, research EEGs, and sample collections at each visit. This data will be maintained on a secure research database. Samples collected will be used for functional testing and the generation of iPSC cell lines, for neuronal reprogramming and phenotyping.",[23,24,25,26],"Genetic Disease","Chopra-Amiel-Gordon Syndrome","CAGS","ANKRD17",[28,29,30,26,31,25,32],"Syndrome","Neurodevelopmental","ANKRD17 Loss of function","Rare Disease","Chopra-Amiel-Gordon","RECRUITING","2026-02-12",{"date":36,"type":37},"2026-02-17","ACTUAL",{"date":39,"type":37},"2022-08-27",{"date":41,"type":19},"2030-12",{"name":43,"class":44},"Boston Children's Hospital","OTHER"]
