What is GNB1 encephalopathy?

GNB1 encephalopathy is caused by changes in the GNB1 gene. These changes can keep the gene from working as it should. GNB1 encephalopathy is also called GNB1-E.

Key Role

GNB1 plays a key role in cell communication and is important for early development, learning and memory, and other cell activities.

Symptoms

Many people who have GNB1 encephalopathy have:

  • Intellectual disability
  • Low muscle tone, or hypotonia
  • Brain disorders
  • Seizures
  • Movement issues

Do people who have GNB1 encephalopathy look different?

Most people who have GNB1 encephalopathy do not look different. Some people may have:

  • larger than average head size, or macrocephaly
  • Eyes that are further apart
  • Cleft palate

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 GNB1 Encephalopathy.

Research Article Summaries

We currently do not have any article summaries for GNB1, but we add resources to our website as they become available.

The information available about GNB1 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 GNB1 articles can be found here.
