Neurofibromatosis 2

Neurofibromatosis 2 (NF2) is a genetic disorder in which tumors form on the nerves of the brain and spine (the central nervous system).

Although it has a similar name to neurofibromatosis type 1, it is a different and separate condition.


NF2 is passed down through families in an autosomal dominant pattern. This means that if one parent has NF2, any child of that parent has a 50% chance of inheriting the condition.

The main risk factor is having a family history of the condition.


Symptoms of NF2 include:

  • Balance problems
  • Cataracts at a young age
  • Changes in vision
  • Coffee-colored marks on the skin (café-au-lait)
  • Headaches
  • Hearing loss
  • Ringing and noises in the ears
  • Weakness of the face

Exams and Tests

Signs include:

  • Brain and spinal tumors
  • Hearing-related (acoustic) tumors
  • Skin tumors

Tests include:

  • Genetic testing
  • Medical history
  • MRI
  • Physical examination


Acoustic neuromas can be observed, or treated with surgery or radiation.

Patients may benefit from genetic counseling.

Every year, patients with NF2 should be evaluated with:

  • MRI of the brain and spinal cord
  • Hearing and speech evaluation
  • Eye exam
