Epilepsy is a common feature of GRIN1-related disorders, and is present in approximately two-thirds of children with this condition. Statistics show that in 2011, the global life expectancy of anyone born with the disorder was 70 years old. Mutations in GRIN1 impair this process and lead to abnormal functioning of NMDA receptors, resulting in epilepsy and associated developmental differences. More detailed information for clinicians ordering genomic testing can be found here. A combination of seizure medications is typically used to control the different seizure types.

Here's how it works. The following information represents typical management recommendations for individuals with developmental delay/ intellectual disability in the United States; standard recommendations may vary from country to country. A multigene panel that includes GRIN1 and other genes of interest (see Differential Diagnosis) is most likely to identify the genetic cause of the condition while limiting identification of variants of uncertain significance and pathogenic variants in genes that do not explain the underlying phenotype. For kids like Ryan with a genetic epilepsy, understanding the cause can make a critical difference in controlling seizures. De novo mutations in GRIN1 cause extensive bilateral polymicrogyria.
