Summary Summary


Listen
Charcot-Marie-Tooth disease is a group of disorders that affect the peripheral nerves, the nerves running from outside the brain and spine.[1] Defects in many different genes cause different forms of this disease. Common symptoms may include foot drop, foot deformity, loss of lower leg muscle, numbness in the foot or leg, “slapping" gait (feet hit the floor hard when walking), and weakness of the hips, legs, or feet.[1] There is currently no cure for Charcot-Marie-Tooth disease, but physical therapy, occupational therapy, braces and other orthopedic devices, pain medication, and orthopedic surgery can help manage and improve symptoms.[2]

There are over 40 types of Charcot-Marie-Tooth disease. You can search for more information on a particular type of Charcot-Marie-Tooth disease from the GARD Home page. Enter the name of the condition in the GARD search box, and then select the type from the drop down menu.

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Treatment Treatment


Listen

The resources below provide information about treatment options for this condition. If you have questions about which treatment is right for you, talk to your healthcare professional.

Management Guidelines

  • Project OrphanAnesthesia is a project whose aim is to create peer-reviewed, readily accessible guidelines for patients with rare diseases and for the anesthesiologists caring for them. The project is a collaborative effort of the German Society of Anesthesiology and Intensive Care, Orphanet, the European Society of Pediatric Anesthesia, anesthetists and rare disease experts with the aim to contribute to patient safety.

Find a Specialist Find a Specialist


Listen

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

  • The Charcot-Marie-Tooth Association (CMTA) has a "Resource Search" section on its website, which can be used to find physicians and other state and national resources. It also has extended search options which can be used to narrow down your search to a specified distance from a particular zip code. To perform a resource search on the CMTA's Web site, click here.
  • The Muscular Dystrophy Association can help you find a doctor who knows about Charcot-Marie-Tooth disease. Click on the link to search for specialty clinics nearest you.
  • Services to enhance mobility and independent living are available in each community through the Muscular Dystrophy Association's local network of chapters and field offices. Click here to read more about this service.
  • The Muscular Dystrophy UK provides information regarding the Joseph Patrick Trust which provides financial support for specialist equipment. Click on the link to read more about this trust.

Research Research


Listen

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 related to Charcot-Marie-Tooth disease. Click on the link to go to ClinicalTrials.gov to read descriptions of these studies.

    Please note: Studies listed on the ClinicalTrials.gov website are listed for informational purposes only; being listed does not reflect an endorsement by GARD or the NIH. We strongly recommend that you talk with a trusted healthcare provider before choosing to participate in any clinical study.
  • 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".

Patient Registry

  • The Inherited Neuropathies Consortium is a team of doctors, nurses, research coordinators, and research labs throughout the U.S., working together to improve the lives of people with Charcot Marie Tooth disease through research. The Inherited Neuropathies Consortium has a registry for patients who wish to be contacted about clinical research opportunities.

Organizations Organizations


Listen

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
