Below is a summary for the TCF20 gene observed in research publications. This is not meant to take the place of medical advice.

What is TCF20-related Syndrome?

TCF20-related syndrome happens when there are changes to the TCF20 gene. These changes can keep the gene from working as it should.

Key Role

The TCF20 gene plays a key role in the development of brain cells. It also controls other genes that help guide brain development.


Because the TCF20 gene is important in brain development, many people who have TCF20-related syndrome have:
• Intellectual disability
• Autism

Do people who have TCF20-related syndrome look different?

People who have TCF20-related syndrome may look different. Some people have a condition called craniosynostosis, in which some parts of the skull join too early. This can cause changes to the skull or facial bones.


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 TCF20.


Research Article Summaries

We currently do not have any article summaries for TCF20, but we add resources to our website as they become available.

The information available about TCF20 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 TCF20 articles can be found here.

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