Neurofibromatosis

Información en español Title

Summary Summary

Neurofibromatosis (NF) is a genetic condition that causes tumors to develop in the nervous system.^[1] There are three types of neurofibromatosis that are each associated with unique signs and symptoms:^[2]^[3]^[1]

Neurofibromatosis type 1 (NF1) causes skin changes (cafe-au-lait spots, freckling in armpit and groin area); bone abnormalities; optic gliomas; and tumors on the nerve tissue or under the skin. Signs and symptoms are usually present at birth.

Neurofibromatosis type 2 (NF2) causes acoustic neuromas; hearing loss; ringing in the ears; poor balance; brain and/or spinal tumors; and cataracts at a young age. It often starts in the teen years.

Schwannomatosis causes schwannomas, pain, numbness, and weakness. It is the rarest type.

All three types of NF are inherited in an autosomal dominant manner. There is no cure for neurofibromatosis. Treatment is aimed at controlling symptoms and may include surgery to remove tumors, radiation therapy and/or medicines.^[2]^[3]

Inheritance Inheritance

Neurofibromatosis is inherited in an autosomal dominant manner.^[1] This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with neurofibromatosis has a 50% chance with each pregnancy of passing along the altered gene to his or her child.

Management Guidelines

GeneReviews provides current, expert-authored, peer-reviewed, full-text articles on type 1 and type 2. These articles describe the application of genetic testing to the diagnosis, management, and genetic counseling of patients with specific inherited conditions.

Research Research

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

Clinical Research Resources

ClinicalTrials.gov lists trials that are studying or have studied Neurofibromatosis. Click on the link to go to ClinicalTrials.gov to read descriptions of these studies.
The Research Portfolio Online Reporting Tool (RePORT) provides access to reports, data, and analyses of research activities at the National Institutes of Health (NIH), including information on NIH expenditures and the results of NIH-supported research. Although these projects may not conduct studies on humans, you may want to contact the investigators to learn more. To search for studies, enter the disease name in the "Text Search" box. Then click "Submit Query".

Organizations Organizations

Nonprofit support and advocacy groups bring together patients, families, medical professionals, and researchers. These groups often raise awareness, provide support, and develop patient-centered information. Many are the driving force behind research for better treatments and possible cures. They can direct people to research, resources, and services. Many groups also have experts who serve as medical advisors. Visit their website or contact them to learn about the services they offer.

NCATS Co-Sponsored Conferences

Developing Endpoints to Facilitate Clinical Trials in Rare Diseases Tuesday, November 17, 2015 - Friday, November 20, 2015
Location: Bethesda, MD
Description: The Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) International Collaboration holds a winter annual conference each year to develop and to discuss novel outcome measures for clinical trials of neurofibromatosis and schwannomatosis, a group of related tumor suppressor syndromes. The annual winter conference has been very successful in stimulating international collaboration among the many different specialists involved in the treatment of these rare conditions. The 2015 conference theme is to develop consensus-driven outcome measures for clinical trials in patients with rare disease such as neurofibromatosis and schwannomatosis.

Children's Tumor Foundation 2014 Neurofibromatosis (NF) Conference Saturday, June 7, 2014 - Tuesday, June 10, 2014
Location: Washington , D.C.
Description: In order to stimulate exchange between basic scientists and clinical investigators, a number of sessions will be organized to discuss preclinical models and findings side by side with clinical findings and current management in patients. The hope is that this exchange will promote the translation of preclinical findings into clinical trials. Moreover, invited speakers outside of the NF community will add to the scientific diversity and stimulate discussions and promote new collaborations.
