TRIO

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

What is TRIO-related syndrome?

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

Key Role

The TRIO gene plays a key role in the basic function of the cell.

Symptoms

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

  • Intellectual disability
  • Motor and language delays
  • Behavior issues, such as autism

Do people who have TRIO-related syndrome look different?

People who have TRIO-related syndrome may look different. One study of 10 people found that one-half had a small lower jaw and facial asymmetry, meaning the left half of the face looked different from the right half. Some have short tapered fingers.

How many people have ADNP-related syndrome?

As of 2020, about 20 people in the world with changes in the TRIO gene had been described in the medical literature.

Research Article Summary

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

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

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