Are any other muscular dystrophies caused by mutations in the dysferlin gene?
There is a condition referred to as “distal anterior compartment myopathy” (DACM) which is very similar to Miyoshi myopathy except that the first muscles affected are the muscles in the front of the calf, rather than in the back. There also have been some patients found to have dysferlin gene mutations whose symptoms do not precisely match the clinical features of MM, LGMD2B, or DACM. A more general term for all muscular dystrophies caused by mutations in dysferlin is “dysferlinopathy” (see next question).
