Neurofibromatosis is a genetic disorder that causes tumors in the nervous system. Tumors develop in the nerves or the tissue that surrounds the nerves, called the myelin sheath. Neurofibromatosis is divided into three types, neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and schwannomatosis. The type is determined by the specific genes that are affected.

This article discusses NF2. These tumors tend to arise in the central nervous system. The eighth cranial nerve, which affects hearing and balance, is the most commonly involved nerve.
