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

- Nf1. A rare genetic condition that causes brown spots and tumors on the skin, freckling in skin areas not exposed to the sun, tumors on the nerves, and developmental changes in the nervous system, muscles, bone, and skin
- Type 1 (peripheral) neurofibromatosis (von recklinghausen's disease), is the most common type of neurofibromatosis. It is characterized clinically by cutaneous and subcutaneous tumors with patches of hyperpigmentation. The hyperpigmented skin areas, are present from birth and found anywhere on the body surface. They can vary markedly in size and color. The dark brown areas are called cafe-au-lait spots. The multiple cutaneous and subcutaneous tumors are nerve sheath neoplasms, called neurofibromas. They can develop anywhere along the peripheral nerve fibers. Neurofibromas can become quite large, causing a major disfigurement, eroding bone, and compressing various peripheral nerve structures. Type 1 neurofibromatosis has dominant inheritance, with a gene locus on the proximal long arm of chromosome 17
