Your unique experience could hold the clues that scientists need to find answers for you and others with rare genetic disorders.

What is CSNK2B-related syndrome?

CSNK2B-related syndrome happens when there are changes to the CSNK2B gene. These changes can keep the gene from working as it should. CSNK2B-related syndrome is also called Poirier-Bienvenu neurodevelopmental syndrome.

The CSNK2B protein interacts with CSNK2A1, which is another Simons Searchlight gene.

Key Role

CSNK2B plays an important role in brain function.


Because the CSNK2B gene is important in the development and function of brain cells, many people who have CSNK2B-related syndrome have:

  • Intellectual disability
  • Speech issues
  • A history of seizures
  • A diagnosis of epilepsy

Do people with CSNK2B-related syndrome look different?

People who have CSNK2B-related syndrome may look different, but the specific set of features are unclear.


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 CSNK2B.


Research Article Summaries

We currently do not have any article summaries for CSNK2B, but we add resources to our website as they become available.

The information available about CSNK2B 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 CSNK2B articles can be found here.
