Tack, a 24-year old lad is suffering from NeurofibromatosisType 2 (NF2). It is a very rare genetic disease and is inherited. The main manifestation of this disorder is the development of symmetric, non-malignant brain tumours in the region of the cranial nerve VIII, which is the auditory-vestibular nerve that transmits sensory information from the inner ear to the brain. Most people with this condition also experience problems in their eyes. NF II is caused by mutations of the "Merlin" gene which probably influences the form and movement of cells. The principal treatments consist of neurosurgical removal of the tumors and surgical treatment of the eye lesions. There is no therapy for the underlying disorder of cell function caused by the genetic mutation.
