What is NF?

Neurofibromatosis (NF) is a term that refers to at least three distinct, hereditary disorders caused by an abnormality in a gene. These disorders include neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and schwannomatosis. While NF1 is caused by an alteration, or mutation, in a gene located on chromosome 17, both NF2 and schwannomatosis are caused by mutations in genes located on chromosome 22.
