Learn About Rare Disease >    SYNGAP1


SYNGAP1 is a rare neurodevelopmental disorder characterized by intellectual disabilities and seizures. Patients can present with a spectrum of severity.

Key characteristics and symptoms of SYNGAP1


Intellectual disability: All patients with SYNGAP1 have some form of intellectual disability that ranges from moderate to severe. Some patients are diagnosed with autism.

Epilepsy: About 2/3 of patients with SYNGAP1 experience seizures. In some cases, seizures are easy to control while others may require multiple medications to gain seizure control.


  • Low muscle tone
  • Small head size
  • Behavioral problems
  • Language impairment
  • Eating difficulties

How is SYNGAP1 diagnosed?

A diagnosis of SYNGAP1 is suspected based on symptoms but is confirmed through genetic testing that identifies a mutation in the SYNGAP1 gene.

How is SYNGAP1 treated?

Currently there is no cure for SYNGAP1. Patients are treated for their symptoms, not for the underlying cause of the disease. Medications and therapies can be used to alleviate symptoms. Researchers are analyzing patient data to better understand the condition so a cure may be found.
