What is PPP2R1A -related syndrome?

PPP2R1A -related syndrome happens when there are changes to the PPP2R1A gene. These changes can keep the gene from working as it should.

Key Role

The PPP2R1A gene plays an important role in brain cells.


Because the PPP2R1A gene is important for the brain, some people may have:

  • Difficulty speaking, or inability to speak
  • Inability to walk
  • Low muscle tone
  • Seizures
  • Brain changes seen on magnetic resonance imaging (MRI)
  • Heart defects at birth
  • Attention deficit hyperactivity disorder, also called ADHD
  • Feeding issues

Do people who have PPP2R1A -related syndrome look different?

People who have PPP2R1A -related syndrome may look different. Appearance can vary and can include some but not all of these features:

  • Taller than average height
  • Smaller or larger than average head size
  • Wide-set eyes
  • Open mouth

How many people have PPP2R1A -related syndrome?

As of 2022, about 50 people with PPP2R1A -related syndrome have been described in medical research.


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  PPP2R1A .


Research Article Summaries

We currently do not have any article summaries for  PPP2R1A , but we add resources to our website as they become available.

The information available about  PPP2R1A  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 PPP2R1A  articles can be found here.
