KDM5B

Below is a summary for the KDM5B gene observed in research publications. This is not meant to take the place of medical advice.

What is KDM5B-related syndrome?

KDM5B-related syndrome happens when there are changes to both copies of the KDM5B gene. These changes can keep the gene from working as it should.

Key Role

The KDM5B gene plays an important role in human development.

Symptoms

Because the KDM5B gene is important for the proper function of the body’s cells, some people may have:

Heart defects
Difficulty feeding
Global development delay
Intellectual disability
Speech difficulty
Issue with walking
Brain changes seen on magnetic resonance imaging (MRI)
Learning challenges

Do people who have KDM5B-related syndrome look different?

People with KDM5B-related syndrome may look different. Appearance can vary and can include some but not all of these features:

Rounded end of the nose
Thinner than average lips
Longer than average head shape
Droopy eyelids
Eyes that are not aligned

How many people have KDM5B-related syndrome?

As of 2022, about 13 people with KDM5B-related syndrome have been described in medical research.

Research Article Summaries

We currently do not have any article summaries for KDM5B, but we add resources to our website as they become available.

The information available about KDM5B 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 KDM5B articles can be found here.

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