nervous system
• mice exhibit compacted sheaths with a regular periodic structure like wild-type mice, however, the periodicity is expanded by 21%; majority of this increase derives from the extracellular space

N normal phenotype
nervous system
• myelin contains disordered packing of membranes and shows a swollen phase that increases to about 40% of the total by 7 hours in x-ray diffraction analysis
• however, myelin does not show altered period or altered intermembrane distances
• total myelin diffraction is reduced by about half, indicative of both hypomyelination and demyelination
• total myelin diffraction is reduced by about half, indicative of both hypomyelination and demyelination

behavior/neurological

muscle
• muscle atrophy in the hindlimbs

nervous system
• myelin contains disordered packing of membranes
• 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
• hypomyelination with occasional nude axons
