The online Gene Guide includes more information about SYNCRIP such as the chance of having another child with this condition, behavior and development concerns linked to SYNCRIP-related syndrome or specialists to consider for people with this condition. Share this resource with family members or your clinical providers.

SYNCRIP-related syndrome is also called SYNCRIP related neurodevelopmental disorder (SYNCRIP-RNDD). For this webpage, we will be using the name SYNCRIP-related syndrome to encompass the wide range of variants observed in the people identified.

What is SYNCRIP-related syndrome?

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

Key Role

The SYNCRIP gene plays a key role in the development of the brain, heart, and eyes.

Symptoms

Because the SYNCRIP gene is important for brain activity, many people who have SYNCRIP-related syndrome have:

  • Developmental delay, or intellectual disability, or both
  • Autism spectrum disorder or features of autism
  • Seizures
  • Brain changes seen on magnetic resonance imaging (MRI)
  • Low muscle tone, also called hypotonia
  • Eye or vision issues
  • Heart defects
  • Behavioral issues, including attention-deficit/hyperactivity disorder (ADHD) and self-injury behavior
  • Feeding issues
  • Sensorineural hearing loss
  • Genitourinary defects
  • Gastrointestinal issues

How many people have SYNCRIP-related syndrome?

As of 2025, over 30 people with SYNCRIP-related syndrome have been identified in medical research.

GeneReviews

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 are currently no GeneReviews for SYNCRIP.

Research Article Summaries

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

The information available about SYNCRIP 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.
