Basic Information and Research on SYNGAP1

What Is SYNGAP1?

Children born with a SYNGAP1 gene mutation or variant are affected by a variety of symptoms, ranging from mild to severe.

In 2009, the first SYNGAP1 patient was identified and reported in medical literature.

The SYNGAP1 gene is located in the brain and provides instructions for making a protein called SynGAP that plays an important role in nerve cells in the brain.

SynGAP is found at the junctions between nerve cells (synapses) where cell-to-cell communication takes place. Connected nerve cells act as the “wiring” in the circuitry of the brain. Synapses are able to change and adapt over time, rewiring brain circuits, which is critical for learning and memory.

SynGAP helps regulate synapse adaptations and promotes proper brain wiring. The protein’s function is particularly important during a critical period of early brain development that affects future cognitive ability.

What Is the Impact of a SYNGAP1 Gene Mutation?

A SYNGAP1 gene mutation can cause a variety of symptoms.
Symptoms vary between each individual affected and can range from mild to severe. The most common symptoms include:

  • Learning Disabilities
  • Epilepsy
  • Behavioral Challenges
  • Autism
  • Sensory Processing Disorder
