Cross section of brain of inad/inad mouse.

mortality/aging
• died usually 3-8 weeks after birth

nervous system
• neurodystrophic changes with numerous spheroid bodies in nervous tissues such as in the hippocampus, thalamus, hypothalamus, pons, callosal body, striatum, globus pallidus, and the cervical, thoracic and lumbar vertebrae
• axonal dystrophic change represented by spheroid bodies in the gracile tract of the medulla oblongata
• hippocampus is hardly distinguishable due to its thinness and caudal displacement caused by ventricular enlargement

behavior/neurological
• when suspended by tail, the limbs become flexed and then fold toward the trunk compared to controls in which limbs are held extended out from the trunk
• sensory ataxia
• dragging of hindlimbs
• progressive motor paralysis and atrophy of the hindlimbs, which show muscle weakness with foot-droop

limbs/digits/tail
• initially mutants exhibit an abnormal limb posture and later show atrophy of the hindlimbs

adipose tissue
• lean body, particularly in the lower half

growth/size/body
• lean body, particularly in the lower half
