vision/eye
• mice exhibit abnormalities around the periciliary membrane complex and disorganized photoreceptors unlike in wild-type mice
|
• at 28 to 33 months
|
• light-adapted mice exhibit reduced b-wave amplitude compared with wild-type mice
|
• dark-adapted mice exhibit reduced a- and b-waves compared to in wild-type mice
|
hearing/vestibular/ear
• at 2 months, mice exhibit only sporadic loss of hair cells in the mid-basal turn unlike wild-type mice
|
• hair bundles of outer hair cells are compressed in the spiral dimension unlike in wild-type mice
• the angle between the two limbs of the V shape formation is smaller than in wild-type mice resulting in a U shape
• however, interstereocilia links of the outer hair cells are normal
|
• mice exhibit patchy loss of the innermost (shortest) row of outer hair bundles compared with wild-type mice
|
• at 2 and 9 months
|
• profound
