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

What is SRCAP-related Syndrome?

SRCAP-related syndrome happens when there are changes to the SRCAP gene. These changes can keep the gene from working as it should. SRCAP-related syndrome is also known as Floating-Harbor syndrome.

Key Role

The SRCAP gene plays a key role in cell growth.


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

  • Language problems
  • Intellectual disability
  • Delay in bone growth that ends between ages 6 and 12
  • Short height
  • Skeletal changes
  • Changes in facial features

Do people who have SRCAP-related syndrome look different?

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

  • Triangular face
  • Deep set eyes
  • Wide mouth
  • Low set ears
  • Long nose

Some people have behavior problems including temper tantrums; attention deficit hyperactivity disorder, also called ADHD; obsessive compulsive disorder, also called OCD; autism; and anxiety.



People who have SRCAP-related syndrome are often short.


Most people who have SRCAP-related syndrome have some degree of intellectual impairment.


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.

Research Article Summaries

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

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

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