VOICE OF THE COMMUNITY REPORT
Download the Voice of the Community report here. The Simons Searchlight team is happy to share the results from a special survey called The Simons Searchlight Voice of the Community. The results include specific data and information about your community. We extend a big thank you to everyone who contributed their unique information and insight. We couldn’t have done this without you.

What is PPP2R5D-related syndrome?

PPP2R5D-related syndrome happens when there are changes to the PPP2R5D gene. These changes can keep the gene from working as it should.

Key Role

The PPP2R5D protein is an enzyme that plays an important role in the development and function of brain cells.

Symptoms

Because the PPP2R5D gene is important for the brain, some people may have:

  • Autism
  • Intellectual disability
  • Epilepsy
  • Low muscle tone
  • Delayed walking
  • Language impairment
  • Behavior issues or impulses
  • Low blood pressure

Do people who have PPP2R5D-related syndrome look different?

People who have PPP2R5D-related syndrome may look different. Appearance can vary and can include some but not all of these features:

  • Larger than average head size
  • Widely spaced eyes
  • Large, noticeable forehead
  • Low ear lobes
  • Eye issues
  • Bone and joint issues

How many people have PPP2R5D-related syndrome?

As of 2023, about 103 people with PPP2R5D-related syndrome have been described in medical research.

Research Article Summaries

Below, we have summarized research articles about changes in the PPP2R5D gene. We hope you find this information helpful. The information available about PPP2R5D 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 PPP2R5D articles can be found here. You can also visit the Simons Foundation’s SFARI Gene website to see information for researchers about this gene.
