SYNGAP1 encodes SynGAP, a synaptic Ras GTPase-activating protein that is highly enriched in excitatory synapses. SynGAP regulates Ras signaling and controls AMPA receptor trafficking, which is critical for synaptic plasticity and learning. SynGAP interacts with the postsynaptic density (PSD) and is a major substrate for CaMKII. Loss-of-function mutations cause intellectual disability and epilepsy.
High expression in brain, particularly in the hippocampus and cortex. Exclusively neuronal, localized to postsynaptic densities. Expression is developmentally regulated, with highest expression during synaptogenesis.
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| Intellectual Disability | Heterozygous loss | De novo | Synaptic plasticity deficits |
| Autism | Heterozygous loss | De novo | Synaptic dysfunction |
| Epilepsy | Heterozygous loss | De novo | Excitatory/inhibitory imbalance |
| Alzheimer's Disease | Various | Risk factor | Synaptic dysfunction |
