- 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
