Latest IRF2BPL Report | Download Report

Simons Searchlight just released a new report that includes updated information on your genetic community. The report also focuses on development using a survey called the Vineland Adaptive Behavior Scales. Caregivers share how their family members with our genetic condition respond to different skills like communication, self-care, and social skills. This survey helps doctors and researchers understand how our skills change over time.

If you want to help contribute to this research, it’s important to participate in surveys. To view past registry reports and learn more, go to the Simons Searchlight website and click on “Previous Registry Reports.”

What is IRF2BPL-related syndrome?

IRF2BPL-related syndrome happens when there are changes to the IRF2BPL gene. These changes can keep the gene from working as it should.

Key Role

The IRF2BPL gene plays a key role in brain cell function.


Because the IRF2BPL gene is important in the development and function of brain cells, many people who have IRF2BPL-related syndrome have:

  • Seizures
  • Movement issues, such as dystonia, a condition in which muscles contract uncontrollably, and ataxia, a condition that causes uncoordinated movement.
  • In some cases, loss of motor skills.

Do people who have IRF2BPL-related syndrome look different?

People who have IRF2BPL-related syndrome do not look very different.


Autism and developmental delay are common in people who have this type of gene change in IRF2BPL.


Four out of five people in the small study had a speech delay.



Four out of five lost some motor or verbal skills in the first years of life, which is called regression.


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 IRF2BPL.


Research Article Summaries

We currently do not have any article summaries for IRF2BPL, but we add resources to our website as they become available. The information available about IRF2BPL 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 IRF2BPL articles can be found here. You can also visit the Simons Foundation’s SFARI Gene website to see information for researchers about this gene.
