Neurofi bromatosis type 2 Syndrome
Abstract
Neurofi bromatosis type 2 (NF2) is a dominantly inherited syndrome that causes several tumors of the nervous system in affected individuals. Mutations in the NF2 gene cause neurofi bromatosis type 2. The NF2 gene provides instructions for producing a protein called merlin, a cell membrane-related protein that acts as a tumor suppressor. Recent studies estimate that the incidence of neurofi bromatosis type 2 may be as high as 1 in 25,000 people. The symptoms of neurofi bromatosis type 2 are typically noticed between 18 to 22 years of age. The most common fi rst symptom is hearing loss or tinnitus. The clinical presentations of NF2 include bilateral vestibular schwannomas. Other commonly observed nervous system tumors include intracranial meningiomas, schwannomas of other cranial nerves, and spinal tumors. Neuropathies and ocular and cutaneous manifestations are also frequent. The clinical diagnosis of NF2 is based upon the National Institutes of Health consensus criteria as subsequently modifi ed in the Manchester criteria. The differential diagnosis includes sporadic unilateral vestibular schwannomas, neurofi bromatosis type 1, schwannomatosis, and familial meningiomas. Although the treatment of the various clinical manifestations of NF2 is similar to that for sporadic tumors of the same particular type, multidisciplinary team approach is required to minimize the potential morbidities caused by treatment.
