N normal phenotype
behavior/neurological
impaired coordination ( J:310176 )
• 7-month-old mice show decreased balance times on the rotarod
abnormal gait ( J:310176 )
• gait analysis shows increased rear leg sway at 7 months of age

nervous system
hydrocephaly ( J:310176 )
• mice appear normal at birth but develop hydrocephalus during middle age
abnormal brain ventricle morphology ( J:310176 )
• the distribution of GPI-anchored proteins in the ventricular ciliated epithelium is altered in middle-aged mice
abnormal brain ependyma morphology ( J:310176 )
• the number of microvilli on the ependymal surface is decreased in middle-aged mice
decreased brain ependyma motile cilium number ( J:310176 )
• the brain ventricular surface shows an approximate 28% decrease in the number of ependymal cilia at middle age
• however, obvious differences in cilia length are not seen
dilated brain ventricle ( J:310176 )
• ventricular volume is increased by about 18.3% in 6-month-old mice
• however, brains are grossly normal and the cerebral aqueduct is patent

cellular
decreased brain ependyma motile cilium number ( J:310176 )
• the brain ventricular surface shows an approximate 28% decrease in the number of ependymal cilia at middle age
• however, obvious differences in cilia length are not seen
