ARHGEF9

Below is a summary for the ARHGEF9 gene observed in research publications. This is not meant to take the place of medical advice.

What is ARHGEF9-related syndrome?

ARHGEF9-related syndrome happens when there are changes to the ARHGEF9 gene. These changes can keep the gene from working as it should.

Key Role

The ARHGEF9 gene plays a key role in the communication that takes place between brain cells.

Symptoms

Because the ARHGEF9 gene is important in the function of brain cells, many people who have ARHGEF9-related syndrome have:

  • Intellectual disability
  • Epilepsy
  • Changes in facial features

Do people who have ARHGEF9-related syndrome look different?

People who have ARHGEF9-related syndrome may look different. The differences are often more noticeable in males. Appearance can vary and can include some but not all of these features:

  • Large, fleshy earlobes
  • Large jaw, also called prognathism
  • A sunken appearance in the middle of the face, also called midface hypoplasia

GeneReviews

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 ARHGEF9.

Research Article Summaries

We currently do not have any article summaries for ARHGEF9, but we add resources to our website as they become available.

The information available about ARHGEF9 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.
