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

What is CTCF -related syndrome?

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

Key Role

The CTCF gene plays a key role in the growth of the brain and the body. The CTCF gene helps to control other genes in the brain.


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

  • Developmental delay
  • Intellectual disability
  • Autism and other behavior concerns

Do people who have CTCF -related syndrome look different?

About one-half of those who have CTCF -related syndrome have a small head. Otherwise, people who have CTCF -related syndrome do not look very different.


About three-quarters of those who have the syndrome have behavior issues, including autism.



Learning challenges vary widely in people who have the syndrome. Some have a severe intellectual disability. Others have an average IQ.

Feeding and digestion issues

More than three-quarters of those who have the syndrome have a hard time eating and may not gain enough weight, also called failure to thrive. Some people need a feeding tube.


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  CTCF .


Research Article Summaries

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

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

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