The molecular pathophysiology of Fragile X Syndrome (FXS) involves loss of FMRP function, leading to dysregulated protein synthesis and synaptic dysfunction.[1][2]
mGluR Signaling Dysregulation
Synaptic Protein Synthesis
Ion Channel Dysfunction
| Gene/Protein | Function | Role in FXS |
|---|---|---|
| FMR1 | Fragile X mental retardation protein | Lost/reduced function |
| FMR1 | mRNA translation repressor | Cannot suppress local translation |
| mGluR5 | Glutamate receptor | Overactive signaling |
| NMDA | Glutamate receptor | Altered trafficking |
| AMPA | Glutamate receptor | Enhanced internalization |
| PSD-95 | Synaptic scaffolding | Dysregulated expression |
| Arc | Activity-regulated cytoskeleton protein | Elevated levels |
| CaMKII | Calcium/calmodulin-dependent protein kinase | Altered regulation |
| MAP1B | Microtubule-associated protein | Synaptic dysfunction |
| CYFIP1 | FMRP interacting protein | Upregulated |
