When do symptoms of neurofibromatosis type 2 (NF2) appear?

Signs of neurofibromatosis type 2 (NF2) may be present in childhood but are so subtle that they can be overlooked, especially in children who don't have a family history of the disorder. Typically, symptoms of NF2 are noticed between 18 and 22 years of age. The most frequent first symptom is hearing loss or ringing in the ears (tinnitus). Less often, the first visit to a doctor will be because of disturbances in balance, visual impairment (such as vision loss from cataracts), weakness in an arm or a leg, seizures, or skin tumors.

This answer is based on source information from the National Institute of Neurological Disorders and Stroke.
