mortality/aging
• very few mice survive to 6 weeks of age

hearing/vestibular/ear
N
• normal ear development
• amplitude of the first wave is significantly diminished in response to a range of frequencies and sound intensities
• latencies are increased
• defects are more severe than in single mutants
• only respond to sounds greater than 55 dB across all frequencies

behavior/neurological
• seen in half of surviving mice

growth/size/body
• runty during adolescence

nervous system
• overall pattern of cochlear innervation is disrupted
• neurites are noticeably defasciculated and the gaps between the bundles are smaller and present only intermittently
• the inner spiral bundle is reduced
• efferent innervation of the cochlea is reduced
