Latest CSNK2A1 Report | Download Report

The latest Simons Searchlight report includes updated information on your genetic community and analyzes developmental growth charts based on the Vineland Adaptive Behavior Scales (Vineland-3) survey. This data shows skills at different ages and helps doctors and researchers understand how these skills change over time. Watch our short video to understand the charts better.

What is CSNK2A1 -related syndrome?

CSNK2A1 -related syndrome happens when there are changes to the CSNK2A1 gene. These changes can keep the gene from working as it should. CSNK2A1 -related syndrome is also called Okur-Chung neurodevelopmental syndrome (OCNDS).

Key Role

The CSNK2A1 gene plays different roles in the body, including helping to control the birth of new cells and helping to control the day to night cycle of cells.


Because the CSNK2A1 gene is important in the development and function of brain cells, many people who have CSNK2A1 -related syndrome have:

  • Physical changes
  • Intellectual disability
  • Other developmental issues

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.

Research Article Summaries

We currently do not have any article summaries for CSNK2A1 , but we add resources to our website as they become available. The information available about CSNK2A1  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 CSNK2A1 articles can be found here.
