Key:
phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological
• muscular tremors noticeable by 12 months of age
• mild incoordination noticeable by 12 months of age

muscle
• development of electron-dense bodies in the mitochondria resulting in swelling and degenerating mitochondria, and disruption of the plasmalemma basal lamina
• the normal myofibrillar architecture of bands and lines disappears and myofilaments disintegrate and become misaligned
• variable muscle fiber size; progressive starting at 3 weeks of age
• exhibit mild muscle fibrosis, however there is no replacement of lost muscle by fat cells
• progressive starting at 9 weeks of age
• progressive starting at 3 weeks of age
• progressive starting at 3 weeks of age
• increased intracellular sodium concentration in muscle; increased severity with age
• progressive degenerative myopathy; increased severity with age

homeostasis/metabolism
• exhibit elevated blood levels of creatine kinase
• exhibit elevated blood levels of pyruvate kinase
