What is SYNGAP1-Related Disorder?
SYNGAP1-related disorder is a rare genetic neurological condition.
It is caused by a change (mutation) in the SYNGAP1 gene, which affects:
- Brain development
- Communication between brain cells (neurons)
This can lead to:
- Intellectual disability
- Developmental delays
- Epilepsy
- Autism-related features
Core Symptoms
Symptoms can vary, but most individuals experience:
Developmental Delays
- Delayed speech
- Delayed movement (sitting, walking)
- Low muscle tone (hypotonia)
Epilepsy
- Around 80–85% develop seizures
- Often begins in early childhood
- Usually generalized epilepsy
Intellectual Disability
- Typically moderate to severe
- Affects learning, memory, and understanding
Autism & Behaviour
- Around 50% are diagnosed with Autism Spectrum Disorder
-
May include:
- Hyperactivity
- Anxiety
- Impulsivity
- Sleep difficulties
Underlying Cause
The condition is linked to the SYNGAP1 gene, which helps regulate brain activity.
- The gene produces a protein important for synapses (connections between brain cells)
- A mutation causes haploinsufficiency (not enough protein)
-
This leads to:
- Overactive (hyperexcitable) brain signals
- Disrupted learning and behaviour
Diagnosis & Management
Diagnosis
-
Genetic testing:
- Chromosomal microarray
- Whole-exome sequencing
Treatment & Support
There is no cure, so support focuses on managing symptoms.
A multidisciplinary approach may include:
- Pediatric neurologists
- Speech and language therapists
- Occupational therapists
- Medication for seizures and behaviour
Support & Resources
- SynGAP Research Fund
- Simons Searchlight
- Child Neurology Foundation
These organisations provide:
- Family support networks
- Research updates
- Educational resources
📖 2. Easy Read Version
What is SYNGAP1?
SYNGAP1 is a rare genetic condition.
It affects:
- Brain development
- How brain cells communicate
What does it cause?
A person may have:
- Learning difficulties
- Delayed speech and movement
- Seizures (epilepsy)
- Autism traits
Common signs
- Late talking or walking
- Low muscle strength
- Seizures
- Trouble sleeping
- Anxiety or hyperactivity
Important to know
- Everyone is different
- Some people need more support than others
- People can still learn and develop skills
Support
- Doctors and therapists can help
- Medicines may help seizures
- Families can get support from organisations
