What is GRIA2-related syndrome?

GRIA2-related syndrome happens when there are changes in the GRIA2 gene. These changes can keep the gene from working as it should. 

The GRIA2 gene codes for a unit of the AMPA receptor. The gene is called GRIA2, and the protein is called GluA2.

Key Role

The GRIA2 gene plays a key role in communication among brain cells. 


Because the GRIA2 gene is important for brain activity, many people who have GRIA2-related syndrome have:

  • Intellectual disability
  • Global developmental delay
  • Speech delay or absent speech
  • Delayed or absent walking
  • Movement discoordination
  • Seizures
  • Autism spectrum disorder

How many people have GRIA2-related syndrome?

As of 2024, at least 39 people with GRIA2-related syndrome have been identified in the medical literature.

Research Articles and References

Below, we have summarized research articles about changes in the GRIA2 gene. We hope you find this information helpful.

The information available about GRIA2 is limited, and families and doctors share a critical need for more information. As we learn more from children who have a change in this gene, we expect this list of resources and information to grow.

Full versions of published research articles can be found on PubMed. PubMed is a National Institutes of Health (NIH) online database that is free. It has a collection of both medical and scientific research articles. A PubMed search for GRIA2 articles can be found here.

You can also visit the Simons Foundation’s SFARI Gene website to see information for researchers about this gene.
