Below is a summary for the KDM3B gene observed in research publications. This is not meant to take the place of medical advice.

What is KDM3B-related syndrome?

KDM3B-related syndrome happens when there are changes to the KDM3B gene. These changes can keep the gene from working as it should.

Key Role

The KDM3B gene plays a key role in brain development.


Because the KDM3B gene is important in the development and function of brain cells, many people who have KDM3B-related syndrome have:

  • Developmental delay
  • Intellectual disability
  • Behavioral concerns

Do people who have KDM3B-related syndrome look different?

People who have KDM3B-related syndrome may be short.


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 KDM3B.


Research Article Summaries

We currently do not have any article summaries for KDM3B, but we add resources to our website as they become available.

The information available about KDM3B 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 KDM3B articles can be found here.
