NF2 Gene is involved in biological pathways relevant to neurodegenerative diseases. It plays important roles in neuronal function, cellular signaling, or stress response mechanisms.
Dysregulation or mutations in this gene/protein contribute to the pathogenesis of Alzheimer's disease, Parkinson's disease, and related neurodegenerative disorders.
NF2 encodes neurofibromin 2, also known as merlin (moesin-ezrin-radixin-like protein) or schwannomin. Merlin is a member of the FERM (4.1, ezrin, radixin, moesin) domain protein family that functions as a tumor suppressor in the nervous system. Unlike NF1, which regulates Ras signaling, NF2 primarily functions as a scaffold protein controlling multiple signaling pathways:
Merlin is unique among tumor suppressors in that it is activated by cell-cell contact and inhibited by growth factor signaling.
NF2 is expressed in:
Expression is highest in:
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| Neurofibromatosis Type 2 | Nonsense, frameshift, splice site | Autosomal dominant | Loss of merlin function, Schwann cell proliferation |
| Schwannomatosis | LOF mutations | Autosomal dominant | Multiple schwannomas without vestibular involvement |
| Meningiomas | LOF mutations | Somatic | Meningeal cell transformation |
| Ependymomas | LOF mutations | Somatic | Ependymal cell transformation |
