Definition

By Mayo Clinic staff

Neurofibromatosis is a genetic disorder that disrupts cell growth in your nervous system, causing tumors to form on nerve tissue. These tumors can occur anywhere in the nervous system, including in your brain, spinal cord, and large and small nerves. Neurofibromatosis is typically diagnosed in childhood or early adulthood.

The tumors are usually noncancerous (benign) and the disorder is usually mild. But effects of neurofibromatosis can range from hearing loss and learning impairment to cardiovascular complications and, in a few cases, cancer.

Neurofibromatosis treatment aims to maximize healthy growth and development and to manage complications as soon as they arise. In cases in which neurofibromatosis causes large tumors or tumors that are pressing on a nerve, surgery may help ease symptoms.
