Below is a summary for the ANK2 gene observed in research publications. This is not meant to take the place of medical advice.

What is ANK2-related syndrome or Ankyrin-B syndrome?

ANK2-related syndrome or Ankyrin-B syndrome happens when there are changes to the ANK2 gene. These changes can keep the gene from working as it should.

What does the ANK2 gene do?

ANK2 plays an important role in brain development and is associated with autism. The gene is also likely associated with language and learning.


Because the ANK2 gene is important in development, many people who have ANK2-related syndrome have:

  • Developmental delay
  • Intellectual disability
  • Speech impairment
  • Behavior issues, including autism
  • Cardiac issues
  • Seizures

Do people who have ANK2-related syndrome look different?

It is unknown if people with ANK2-related syndrome look different.

How many people have ANK2-related syndrome?

As of 2023, about 185 people with ANK2-related syndrome have been identified in medical research. Fewer people have been described in medical detail.

Gene Reviews 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.

ANK2 gene changes are known to be associated with LQTS (the GeneReviews linked here). Long QT syndrome caused by the ANK2 gene change is known as Long QT 4.

Check out the GeneReviews for LQTS.


Research Article Summaries

We currently do not have any article summaries for ANK2, but we add resources to our website as they become available.

The information available about ANK2 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 ANK2 articles can be found here.

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