Multicentric carpotarsal osteolysis syndrome



Other Names:
Multicentric carpo-tarsal osteolysis with or without nephropathy; Idiopathic multicentric osteolysis with or without nephropathy
Categories:

Multicentric carpotarsal osteolysis syndrome is a very rare condition characterized by progressive loss of some of the bones of the hand and feet, usually the carpal (bones of the wrist) and tarsal bones (bones of the ankle), as well as chronic kidney (renal) failure in many cases. The bone problems lead to deformity and disability. Some patients also have intellectual disability and facial abnormalities.[1][2] It is caused by mutations in the MAFB gene.[2] Autosomal dominant inheritance has been described in many families but most cases are sporadic.[3] Treatment is with long-term immunosuppressive therapy.[4]

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.

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.
