Overview
There is no established cause for optic nerve glioma.
Causes
- There is no established cause for optic nerve glioma.
- Sporadic pilocytic astrocytomas usually have a tandem duplication of chromosome 7q34 and associated BRAF-KIAA fusion gene.[1][2] Pilocytic astrocytomas associated with neurofibromatosis type 1 lack this fusion gene. However, it is unknown if the mutation in the BRAF-KIAA fusion gene in the setting of optic nerve glioma is the primary cause of the disease as it is in other pilocystic astrocytomas.
