Characteristic signs of centronuclear myopathies include generalized muscle weakness, atrophy, predominance of type I fibres, and aberrant cell positioning of nuclei and mitochondria. In Great Danes generalized muscle atrophy, exercise intolerance, exercise-induced tremor and muscle wasting characterize the disease. The disease typically starts before 10 months of age, is highly progressive, and most of the affected dogs are euthanized before 18 months of age due to severe debilitating muscle weakness.
