Skeletal muscle biopsies show minicore-like lesions with mitochondrial depletion and sarcomere disorganization, centralized nuclei, and type 1 fiber predominance. Dystrophic changes become apparent in the second decade. Cardiac muscle biopsies show disruption of myocardial architecture, nuclear hypertrophy, and endomysial fibrosis. Sudden death may occurr due to cardiomyopathy.
