NF1 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.
NF1 encodes neurofibromin 1, a tumor suppressor protein that negatively regulates Ras signaling. Neurofibromin contains a GAP-related domain (GRD) that accelerates GTP hydrolysis on Ras proteins, converting active Ras-GTP to inactive Ras-GDP. Loss of neurofibromin function leads to uncontrolled Ras signaling and cell proliferation.
In the nervous system, neurofibromin plays critical roles in:
NF1 is widely expressed in the nervous system:
Expression is regulated by:
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| Neurofibromatosis Type 1 | Nonsense, frameshift | Autosomal dominant | Loss of tumor suppressor function, Ras hyperactivation |
| Cognitive Impairment | Missense | Haploinsufficiency | Impaired synaptic plasticity, cAMP dysregulation |
| Gliomas (NF1-associated) | LOF mutations | Autosomal dominant | Uncontrolled glial proliferation |
| Learning Disabilities | - | Haploinsufficiency | Altered neuronal development |
Therapeutic approaches targeting NF1 include:
