Its function is to Pathogenic variants ("mutations") in the GRIN1 gene cause a spectrum of neurodevelopmental disorders that can include childhood-onset epilepsy, developmental delays, movement disorders, and features of autism spectrum disorder. Research increases what we know about rare diseases so that people can get a diagnosis more quickly and can know what to expect. Treatment of manifestations: Standard treatment of DD/ID, seizures, feeding problems, and behavioral issues. Neurodevelopmental disorders result from impaired growth and development of the central nervous system, which includes the brain and spinal cord, and the nerves connecting them. Where specified, seizures have been classified as epileptic spasms (13%), generalized seizures (68%), and focal seizures (20%). Some organizations build a community of patients and families impacted by a medical condition, like epilepsy, or related conditions, like heart problems, that may also be a symptom in other diseases. Bryson was almost ten years old when a positive gene test confirmed his GRIN mutation - a tiny change in the GRIN1 gene causing all his symptoms.
