| Gene Symbol | SYNGAP1 |
| Full Name | Synaptic Ras GTPase Activating Protein 1 |
| Aliases | SYNGAP1PROTEIN |
| Chromosome | 6p21.3 |
| Function | is a major postsynaptic density (PSD) protein that regulates Ras signaling and controls AMPA receptor trafficking, making it essential for synaptic plasticity, learning, and memory. |
