Distal myopathy

Distal myopathy is a group of rare genetic disorders that cause muscle damage and weakness, predominantly in the hands and the feet rather than in the muscles nearest the trunk. Mutation of many different genes can be the cause, so the label covers several distinct inherited conditions instead of a single disease, and many of the types involve the protein dysferlin. This entry records the condition group as a named clinical category and is not medical advice; diagnosis, genetic testing and care belong to a qualified clinician.
