Neurofibromatosis type 2 (NF2) is a rare autosomal dominant disorder (incidence 1:33 000-40 000) characterized by formation of central nervous system tumors, due to mutation in the NF2 gene on chromosome 22q12. Patients typically present with neurofibromas, optic gliomas, Lisch nodules, hamartomas and cafe au lait spots. The main manifestation of the condition is the development of bilateral benign brain tumors in the nerve sheath of the cranial nerve VIII, which is the "auditory-vestibular nerve" that transmits sensory information from the inner ear to the brain.

Neurofibromatosis 2 (NF2) is an autosomal dominant cancer syndrome characterized by the growth of tumors in the nervous system, most commonly acoustic schwannomas. Tumors seen include bilateral acoustic Schwannomas, Meningiomas, and Ependymomas. The most characteristic manifestation of the disease is the development of symmetric cranial nerve VIII tumors called acoustic schwannomas. The syndrome is caused by CTG trinucleotide repeats, and the classic clinical feature is myotonia, classically with involuntary contractions described as "unable to let go of a doorknob or a jar lid".
