Below is a summary for the GRIN2A gene observed in research publications. This is not meant to take the place of medical advice.

What is GRIN2A-related disorder?

GRIN2A-related disorder happens when there are changes in the GRIN2A gene. These changes can keep the gene from working as it should.

Key Role

The GRIN2A gene plays an important role in brain cell communication, learning, and memory.


Because the GRIN2A gene is important for the brain, some people may have:

  • Intellectual disability
  • Seizures
  • Speech and language difficulties
  • Autistic features
  • Low muscle tone
  • Movement issues

Do people who have GRIN2A-related disorder look different?

People who have GRIN2A-related disorder do not look different.

How many people have GRIN2A-related disorder?

As of 2022, about 138 people in the world with GRIN2A-related disorder have been identified clinically.


Support Resources



GeneReviews are a great resource to bring to your child’s clinicians. These publications provide a summary of current research on genetic conditions and information on ongoing care.

Research Article Summaries

Below, we have summarized research articles about changes in the GRIN2A gene. We hope you find this information helpful.

The information available about GRIN2A 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 GRIN2A articles can be found here.

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