hearing/vestibular/ear

abnormal cochlear hair cell morphology ( J:154318 )

• by P21, some hair cells in the basal turn of the cochlea exhibit fused stereocilia and membrane ruffling at the apical cell surface unlike in wild-type mice

cochlear hair cell degeneration ( J:154318 )

• profound by P90

abnormal auditory brainstem response ( J:154318 )

• by 3 weeks of age

increased or absent threshold for auditory brainstem response ( J:119820 )

• auditory threshold of more than 90 dB, indicating that lines are severely hearing impaired in 8- to 12-weeks old animals

absent distortion product otoacoustic emissions ( J:154318 )

• at 3 weeks of age

nervous system

abnormal cochlear hair cell morphology ( J:154318 )

• by P21, some hair cells in the basal turn of the cochlea exhibit fused stereocilia and membrane ruffling at the apical cell surface unlike in wild-type mice

cochlear hair cell degeneration ( J:154318 )

• profound by P90

cochlear ganglion degeneration ( J:154318 )

• profound by P90

behavior/neurological

decreased startle reflex ( J:119820 )

• low auditory startle response
