Centronuclear myopathy (CNM)

Myopathy is one of hereditary diseases that cause deficiency of type 2 muscular fibers. First clinical signs are evident as early as 3 to 4 month of age. Clinical features in male and female pups include hypotonia, generalized muscle weakness, abnormal postures, stiff hopping gait, exercise intolerance and increased collapse when exposed to cold. There is evidence of skeletal muscle atrophy, particularly involving muscles of the head and tendinous areflexia. In all reported cases, histopathological evaluation of muscle biopsies has demonstrated a characteristic centralization of myonuclei, often located in areas devoid of myofibrils with mitochondrial aggregation.
