Neurofibromatosis (NF) is a genetic disease that causes tumors to develop in the nervous system. There are three types of neurofibromatosis that are each associated with unique signs and symptoms:
Neurofibromatosis type 1 (NF1) causes skin changes (cafe-au-lait spots, freckling in armpit and groin area); bone abnormalities; optic gliomas; and tumors on the nerve tissue or under the skin. Signs and symptoms are usually present at birth.
All three types of NF are inherited in an autosomal dominant manner. There is no cure for NF. Treatment is aimed at controlling symptoms and may include surgery to remove tumors, radiation therapy, and/or medicines.

Neurofibromatosis is inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with neurofibromatosis has a 50% chance with each pregnancy of passing along the altered gene to his or her child.
