What Is SYNGAP1? Quiz

 

The Basics:

• SYNGAP1 is a gene that encodes the protein SynGAP, which plays a crucial role at synapses—the communication junctions between neurons—as part of activity-dependent brain wiring and plasticity MedlinePlusWikipedia.

• Proper SynGAP regulation is key for learning, memory, cognition, and overall brain development, especially in early childhood MedlinePlusWikipedia.

Clinical Impact:

• Pathogenic variants (often de novo) in SYNGAP1 cause haploinsufficiency, where one copy of the gene is nonfunctional, reducing SynGAP protein levels MedlinePlusWikipedia.

• This results in a neurodevelopmental disorder characterized by:

  • Intellectual disability of varying severity

  • Global developmental delay

  • Epilepsy (frequently generalized seizure types like absence, atonic, myoclonic, often around age 2)

  • Features of autism spectrum disorder (in ~50–70% of cases)

  • Hypotonia (low muscle tone) and ataxia Beyond the Ion ChannelChildren's Hospital of PhiladelphiaWikipediaEpilepsy Foundation.

Signs & Symptoms:

• Almost everyone with SYNGAP1 mutations has developmental delays and intellectual disability.

• Epilepsy affects 80–98% of individuals, often with seizures that may include reflex triggers like eating or light exposure WikipediaEpilepsy Foundation.

• Other frequent issues include sleep disturbances, behavior challenges, feeding difficulties, high pain threshold, vision issues, and movement coordination problems Children's Hospital of PhiladelphiaWikipedia.

Cause & Inheritance:

• Mostly de novo (spontaneously occurring) genetic changes, meaning parents typically don’t carry the mutation Simons SearchlightWikipedia.

• Classified as autosomal dominant: only one mutated copy leads to the syndrome Simons SearchlightWikipedia.

• Recurrence risk to subsequent children is around 1% unless parental mosaicism is identified; if a parent carries the mutation, each child has around a 50% chance of inheritance Simons SearchlightWikipedia.

Treatment & Prognosis:

• There is no cure currently.

• Treatments are symptomatic and supportive: anti-seizure medication (or devices if medication-resistant), speech and occupational therapy, physical therapy, behavioral and feeding support, developmental interventions Probably GeneticWikipedia.

• Emerging research includes statins (to modulate Ras signaling) and antisense oligonucleotides to upregulate SynGAP expression, though these remain at pre‑clinical or early research stages WikipediaWikipedia.

📝 About Quizzes on SYNGAP1

• I didn’t find quizzes specifically featuring SYNGAP1 on Study.com or similar platforms.

• Given its rarity and highly specialized nature, most public educational resources focus on general neurogenetics rather than gene‑specific quizzes.

• You’ll likely need to create your own quiz or study tool.
