What is MEF2C -related syndrome?

MEF2C -related syndrome happens when there are changes to the MEF2C gene. These changes can keep the gene from working as it should.

Key Role

The MEF2C gene is important for muscle and brain cells.


Because the MEF2C gene is important in the development and function of brain cells, many people who have MEF2C -related syndrome have:

  • Intellectual disability
  • Speech difficulties or no speech
  • Delayed walking
  • Autism or features of autism

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.

There is currently no GeneReviews for  MEF2C .


Research Article Summaries

We currently do not have any article summaries for MEF2C , but we add resources to our website as they become available.

The information available about MEF2C is limited, and families and doctors share a critical need for more information. As we learn more from children who have this gene change, we expect our 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 MEF2C articles can be found here.
