Natural History Study of Infants and Children With CNKSR2-Associated Neurodevelopmental Disorders and Epilepsy
This prospective natural history study is being conducted to define the electroclinical, neurodevelopmental, and behavioral characteristics of CNKSR2 epilepsy aphasia syndrome (EAS) and intellectual disability (ID) in children aged 6 to 21 years old with CNKSR2 mutations. The data collected from this study will serve as an external control to eventual clinical trials examining precision medicine investigational therapeutics that aim to improve the seizure burden and neurodevelopmental outcomes in patients with CNKSR2 EAS/ID.
• Age between 6 and 21 years (inclusive) at time of consent.
• Confirmed CNKSR2 mutation, as demonstrated by genetic testing and confirmed by the investigators.
• Confirmed intellectual disability or developmental delays, as defined by the American Academy of Pediatrics (Moeschler, J, et al. 2014).
