Clinical Information
- A group of disorders characterized by an autosomal dominant pattern of inheritance with high rates of spontaneous mutation and multiple neurofibromas or neurilemmomas. Neurofibromatosis 1 (generalized neurofibromatosis) accounts for approximately 95% of cases, although multiple additional subtypes (e.g., neurofibromatosis 2, neurofibromatosis 3, etc.) have been described. (from neurochirurgie 1998 nov;44(4):267-72)
- An autosomal dominant hereditary neoplastic syndrome. Two distinct clinicopathological entities are recognized: neurofibromatosis type 1 and neurofibromatosis type 2. Neurofibromatosis type 1 is associated with the presence of cafe-au-lait cutaneous lesions, multiple neurofibromas, malignant peripheral nerve sheath tumors, optic nerve gliomas, and bone lesions. Neurofibromatosis type 2 is associated with the presence of schwannomas, meningiomas, and gliomas.
