mortality/aging
|
• early mortality is observed in severely affected mutants
|
behavior/neurological
|
• progressive with age, animals rest on abdomen instead of limbs
|
|
• mutants often maintain limbs in an abnormal posture, progressing from a flexor to an extensor posture
|
craniofacial
growth/size/body
muscle
|
• an increase in apoptosis is observed in mutant myoblasts infected with adenoviral-cre (to completely obliterate expression) during induced differentiation
|
|
• 2 weeks after a muscle crush injury in the tibialis anterior, muscle fibers that have regenerated are not continuous and are interspersed with encapsulated cellular debris

|
behavior/neurological
|
• when placed on a slippery surface, mutants are unable to position their limbs properly
• mutants exhibit spastic movements
|
|
• abnormal hindlimb extension reflexes
|
muscle
|
• initial contact between sensory Ia afferent neurons and myotubes occurs but subsequent development of muscle spindles is impaired
|
|
• absence of muscle spindles
|
nervous system
|
• initial contact between sensory Ia afferent neurons and myotubes occurs but subsequent development of muscle spindles is impaired
|
|
• absence of muscle spindles
|
|
• synapses at neuromuscular junctions contain reduced numbers of acetylcholine receptors
|
|
• mutants exhibit reduced synaptic transmission at neuromuscular junctions; mepc amplitudes are reduced by about 15% compared to wild-type
