Morphological defects around the periciliary membrane complex in Whrntm1Tili/Whrntm1Tili photoreceptors

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
• profound

nervous system
