Living with Neurofibromatosis

A genetic condition that causes tumors to grow in the nervous system, with three types.

Understanding Neurofibromatosis

Neurofibromatosis (NF) is a genetic condition that causes tumors to develop in the nervous system.

There are three types, each with different signs. NF1 causes skin changes, bone differences, optic gliomas, and tumors on nerves or under the skin, usually present at birth. NF2 causes acoustic neuromas, hearing loss, ringing in the ears, poor balance, brain and spinal tumors, and early cataracts. Schwannomatosis is the rarest type and causes schwannomas, pain, numbness, and weakness.

Signs & symptoms

GARD describes different features for each type:

  • Café-au-lait spots and freckling (NF1)
  • Tumors on nerves or under the skin (NF1)
  • Hearing loss and ringing in the ears (NF2)
  • Poor balance (NF2)
  • Pain, numbness, and weakness (schwannomatosis)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Children's Tumor Foundation, Neurofibromatosis Midwest and Neurofibromatosis Network may keep lists of experts for this condition.

Everyday life

Living with a rare condition is easier with support.

  • Connect with Children's Tumor Foundation and other patient organizations
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Which type of neurofibromatosis do I have?
Should we have genetic testing?
How often should I be checked for new tumors?

Quick facts

InheritanceAutosomal Dominant

All three types are inherited in an autosomal dominant manner, which means one changed copy of a gene can be enough to cause it.

Also known as: acoustic neurofibromatosis; central neurofibromatosis; clinical neurofibromatosis; multiple neurofibromatosis; neurofibromatosis syndrome; nf - neurofibromatosis
