NF2; Bilateral acoustic neurofibromatosis; Bilateral vestibular schwannomas; Central neurofibromatosis
Neurofibromatosis 2 (NF2) is a disorder in which tumors form on the nerves of the brain and spine (the central nervous system). It may be passed down (inherited) in families.
Although it has a similar name to neurofibromatosis type 1, it is a different and separate condition.
NF2 is caused by a mutation in the gene NF2. NF2 can be 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. Once someone carries the genetic change, their children have a 50% chance of inheriting it.
Some cases of NF2 occur when the gene mutates on its own. This is called sporadic and is not inherited.
Symptoms of NF2 include:
Signs of NF2 include:
Acoustic tumors can be observed, or treated with surgery or radiation.
People with this disorder may benefit from genetic counseling.
People with NF2 should be regularly evaluated with these tests:
