hearing/vestibular/ear
increased or absent threshold for auditory brainstem response ( J:241137 )
• these mice, homozygous for the c.735A point mutation that causes age related hearing loss and heterozgyous for the ameliorating C57BL/6J-derived modifier, have a 16 kHz ABR threshold at 3 months of age that is less than mice homozygous for the 129S1/SvImJ-derived modifier, proving the C57BL/6J allele dominant
