This website provides information on individuals with pathogenic variants in GRIN1, including clinical data, molecular data, management and research options.
GRIN1-related neurodevelopmental disorder is characterized by developmental delay/intellectual disability (DD/ID), muscular hypotonia, epilepsy and movement disorder. All affected individuals known so far have developmental delay preceding ID of various degree, ranging from mild to usually severe-to-profound. Epilepsy is seen in more than half of affected individuals with numerous possible semiologies. Additional features are muscular hypotonia, movement disorders, autism spectrum disorder, cortical visual impairment and oculogyric crises.
This website was created to share and collect information about clinic, management and research projects to gather more knowledge and provide better treatment of individuals with pathogenic variants in GRIN1.
We invite clinicians who have identified a pathogenic variant in GRIN1 in an individual or parents of a child with a pathogenic variant in GRIN1 to submit their data to the registry. More information regarding the registration, general information, variant analysis and parent organisations can be found on our GRIN Portal: http://grin-portal.broadinstitute.org/.
