Summary
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. Neurofibromatosis type 2 (NF2) causes acoustic neuromas; hearing loss; ringing in the ears; poor balance; brain and/or spinal tumors; and cataracts at a young age. Schwannomatosis causes schwannomas, pain, numbness, and weakness. It is the rarest type. All three types of NF are inherited in an autosomal dominant manner.
