What is CTNNB1-related syndrome?

CTNNB1-related syndrome happens when there are changes to the CTNNB1 gene. These changes can keep the gene from working as it should.

Key Role

The CTNNB1 gene plays a key role in the communication that happens between cells and how cells connect to each other.

Symptoms

Many people who have CTNNB1-related syndrome have:

  • Intellectual disability
  • Speech delay
  • Small head
  • Low muscle tone

Do people who have CTNNB1-related syndrome look different?

People who have CTNNB1-related syndrome can look a little different from others. Appearance can vary and can include some but not all of these features:

  • Thin upper lip
  • Wide-spaced teeth
  • Large nose
  • Fair, thin hair and fair skin

GeneReviews

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 CTNNB1.

Research Article Summaries

Below, we have summarized research articles about changes in the CTNNB1 gene. We hope you find this information helpful. The information available about CTNNB1 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 CTNNB1 articles can be found here. You can also visit the Simons Foundation’s SFARI Gene website to see information for researchers about this gene.
