What is ASXL3 -related syndrome?

ASXL3 -related syndrome happens when there are changes to the ASXL3 gene. These changes can keep the gene from working as it should. ASXL3 -related syndrome is also known as Bainbridge-Ropers syndrome or BRPS.

Key Role

The ASXL3 gene plays a key role in development of the brain and the body. It affects parts of the body including the spinal cord, liver, kidneys, and bone marrow.


ASXL3 -related syndrome can affect communication, social, and learning skills. The effects can be moderate to severe. Because the ASXL3 gene plays a key role in how cells work, many people who have ASXL3 -related syndrome have:

  • Intellectual disability

  • Changes in skull and facial features

  • Feeding problems

  • Delayed growth

  • Curved spine, also called scoliosis


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. Check out the GeneReviews for ASXL3 -related disorder.


Research Article Summaries

Below, we have summarized research articles about changes in the ASXL3 gene. We hope you find this information helpful. The information available about ASXL3 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 ASXL3 articles can be found here.
