phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological
• mice are able to remain for only half as long on an accelerating rotarod compared to wild-type mice

nervous system
• sciatic and digital nerves show thin myelin sheaths, more pronounced distally in digital nerves and progressing with age
• occasional axonal degeneration in digital nerves
• sciatic and digital nerves show onion bulbs and thin myelin sheaths, all more pronounced distally in digital nerves, and progressing with age
• compound muscle action potentials recorded from the small foot muscles after supramaximal proximal sciatic nerve stimulation show a trend toward reduced compound muscle action potential amplitude in both facial and sciatic nerves
• compound muscle action potentials show only minor temporal dispersion, indicating uniform changes throughout myelin
• electrophysiological analysis in sciatic nerves shows slowed nerve conduction and prolonged F-wave latency

behavior/neurological

muscle
• muscle atrophy in the hindlimbs

nervous system
• mice develop a neuromuscular disorder between 4-8 weeks of age
• sciatic nerve shows demyelinating neuropathy
• onion bulbs, signifying myelin destruction followed by attempts to remyelinate, are present at 6 months of age and increase in number with age
• 6 month old mice show demyelination and occasional onion bulbs in both ventral (motor) and dorsal (sensory) roots as well as in sciatic nerve
• hypomyelination with occasional nude axons
