Patients who are already genetically diagnosed with mutations in the dysferlin gene (i.e. LGMD2B/Miyoshi/Dysferlinopathy)

The international patient registry is curated for individuals who have been genetically diagnosed with dysferlinopathy (LGMD2B and Miyoshi Myopathy) through the identification of mutation(s) in the dysfelrin gene.
