Neurofibromatosis affects the growth and development of nerve cell tissues, which can cause tumors to grow on nerves. In turn, it can affect many systems in the body such as the skin, bones and brain.
How does neurofibromatosis affect the body?
Neurofibromatosis can cause skin changes, bone deformities and other problems. The tumors developed, called neurofibromas, are usually noncancerous (benign) and grow on nerves within the body and sometimes under the skin.
In many cases of neurofibromatosis, symptoms are present at birth or develop during childhood. Some people have symptoms that are not noticeable at all. On the other hand, some symptoms cause significant disability.
What causes neurofibromatosis?
Neurofibromatosis is a genetic disorder. An abnormal gene causes each form of the disease.
Types of neurofibromatosis
Neurofibromatosis type 1 (NF1)
NF1 is the most common form of the disease. Also known as von Recklinghausen disease, it affects nerves of the outer parts of the body.

- Multiple birthmarks

- Lisch nodules in the eyes
- Delayed in learning to walk

Neurofibromatosis type 2 (NF2)
NF2 is a less common form of the disease. Also known as bilateral acoustic neurofibromatosis, NF2 mostly affects the central nervous system, causing tumors of the brain and spinal cord.
Symptoms typically develop in the teens or early twenties and include:
- Hearing loss
- Auditory nerve tumors
- Ringing in the ears
- Facial pain/numbness

Your physician may recommend tests to confirm neurofibromatosis including:
