| Genatlas | neurofibromatosis 2,autosomal dominant disorder characterized by tumors of neural-crest origin cells,with biallelic inactivation in schwannomas,meningiomas,mesotheliomas,and testicular anomalies such as presenile lens opacities and retinal hamartomas,(merlin/Schwannomin defect) |
| SWISS-PROT | Schwannomatosis (SCHWA) [MIM:162091]: Schwannomas are benign tumors of the peripheral nerve sheath that usually occur singly in otherwise normal individuals. Multiple schwannomas in the same individual suggest an underlying tumor-predisposition syndrome. The most common such syndrome is NF2. The hallmark of NF2 is the development of bilateral vestibular-nerve schwannomas; but two-thirds or more of all NF2-affected individuals develop schwannomas in other locations, and dermal schwannomas may precede vestibular tumors in NF2-affected children. There have been several reports of individuals with multiple schwannomas who do not show evidence of vestibular schwannoma. Clinical report suggests that schwannomatosis is a clinical entity distinct from other forms of neurofibromatosis.

| SWISS-PROT | Neurofibromatosis 2 (NF2) [MIM:101000]: Genetic disorder characterized by bilateral vestibular schwannomas (formerly called acoustic neuromas), schwannomas of other cranial and peripheral nerves, meningiomas, and ependymomas. It is inherited in an autosomal dominant fashion with full penetrance. Affected individuals generally develop symptoms of eighth-nerve dysfunction in early adulthood, including deafness and balance disorder. Although the tumors of NF2 are histologically benign, their anatomic location makes management difficult, and patients suffer great morbidity and mortality.
