Neurofibromatosis type 2 (NF-2)
Neurofibromatosis type 2 (NF-2 or bilateral acoustic NF) Is estimated to occur in 1 of 30,000 births. The gene for NF-2 is on chromosome 22. NF-2 can be characterized by:
- vestibular schwannomas on both hearing nerves, often resulting in hearing loss and/or balance problems
- cataracts or other visual problems at an early age
- symptoms can appear as early as 2 years, but usually during or after puberty
- other tumors of the central nervous system including the brain and spinal cord tumors of the skin.
