Neurofibromatosis type I is the most common of the three types and is caused by genetic changes in the NF1 gene located on chromosome 17 (17q11.2). This gene encodes a cytoplasmic protein known the neurofibromin, which functions as a tumor suppressor and therefore serves as a signal regulator of cell proliferation and differentiation.
Café au lait spot characteristic of NF1 Diagnostic criteria of neurofibromatosis type I, requiring at least 2 of the mentioned items. [6]The following is a list of conditions and complications associated with NF-1, and, where available, age range of onset and progressive development, occurrence percentage of NF-1 population, method of earliest diagnosis, and treatments and related medical ...
Main symptoms of neurofibromatosis type I [28] Mutations in NF1 are primarily associated with neurofibromatosis type 1 (NF1, also known as von Recklinghausen syndrome). [ 6 ] [ 7 ] NF1 is the most common single gene disorder in humans, occurring in about 1 in 2500–3000 births worldwide. [ 29 ]
Neurofibromatosis type II (also known as MISME syndrome – multiple inherited schwannomas, meningiomas, and ependymomas) is a genetic condition that may be inherited or may arise spontaneously, and causes benign tumors of the brain, spinal cord, and peripheral nerves. The types of tumors frequently associated with NF2 include vestibular ...
A neurofibroma is a benign nerve-sheath tumor in the peripheral nervous system.In 90% of cases, they are found as stand-alone tumors (solitary neurofibroma, solitary nerve sheath tumor [1] or sporadic neurofibroma [1]), while the remainder are found in persons with neurofibromatosis type I (NF1), an autosomal-dominant genetically inherited disease.
Neurofibromatosis type 4 (also known as "Neurofibromatosis variant type") resembles von Recklinghausen's disease, but also presents with cutaneous neurofibromas. [ 1 ] : 552 This is a new development in the NF family.
