This subject of review is the medical conditions of a genetic disorder called, Neurofibromatosis or NF. NF disrupts the cell growth in your nervous system, causing tumors to form on the nerve tissues. Effects of this disorder can range from hearing loss and learning impairments, to cardiovascular complication. There are three types of NF, NF 1, NF 2, and Schwannomatosis. With NF 1, signs usually appear in early childhood. Symptoms can include flat, light brown spots on the skin called cafe’ au lait spots. NF2 is less common than NF1, symptoms of NF2 usually result from the development of vestibular schwannomas in both ears. These benign tumors grow on the nerve that carries sound and balance information from the inner ear to the brain. Schwannomatosis is an extremely rare case of Neurofibromatosis, and was only recently recognized. It mostly seems to affect people in their 20s and 30s. Schwannomatosis causes tumors called schwannomas to develop on cranial, spinal and peripheral nerves, but not on the nerve that carries sound and balance information from the inner ear to the brain.But unlike NF 2 doesn’t cause hearing loss, making it different from NF2.
