Below is a summary for the TANC2 gene observed in research publications. This is not meant to take the place of medical advice. Click HERE for the full gene guide, which includes more information, such as chance of having another child with this condition, or specialists to consider for people with this condition.

What is TANC2-related Syndrome?

TANC2-related syndrome happens when there are changes to the TANC2 gene. These changes can keep the gene from working as it should.

Key Role

The TANC2 gene helps to control the connections between brain cells.


Because the TANC2 gene is important in the development and function of brain cells, many people who have TANC2-related syndrome have:

  • Autism
  • Intellectual disability
  • Delayed language
  • Delayed motor development
  • Seizures

Do people who have TANC2-related syndrome look different?

People who have TANC2-related syndrome may look different. Some people have changes in how their teeth are spaced. A few have a smaller than average head size.


18 out of 20 had speech delays.


Most people who had TANC2-related syndrome had some degree of intellectual disability.


4 out of 12 had anxiety.


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 TANC2.


Research Article Summaries

We currently do not have any article summaries for TANC2, but we add resources to our website as they become available. The information available about TANC2 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 TANC2 articles can be found here. You can also visit the Simons Foundation’s SFARI Gene website to see information for researchers about this gene.
