|
hematopoietic system
|
• large, mature megakaryocytes found
• failed to form proplatelets
|
|
• platelets reduced to near zero
|
behavior/neurological
|
• limb grasping behavior develops by 6 weeks in about half of mice
|
|
• motor activity repressed by auditory stimuli
|
|
• intermittent but long lasting myoclonus in hind limbs of about 2/3 of mice, fully penetrant at 9 weeks of age
• occurs spontaneously but can be triggered by external stimuli such as eating or approaching table edge during free locomotion
|
nervous system
|
• intermittent but long lasting myoclonus in hind limbs of about 2/3 of mice, fully penetrant at 9 weeks of age
• occurs spontaneously but can be triggered by external stimuli such as eating or approaching table edge during free locomotion
|
|
• neuronal nuclei in the gray matter of the spinal cord are swollen and the cytoplasm was thin
