Neurofibromatosis is a group of genetic disorders that cause tumors to form on nerve tissue. These tumors can develop anywhere in the nervous system, including the brain, spinal cord, and nerves. There are three main types: Neurofibromatosis type 1 (NF1), Neurofibromatosis type 2 (NF2), and Schwannomatosis. NF1 is the most common type and it typically presents in childhood, sometimes even in the neonatal period.
