Cochlear hair cell abnormalities in Myo7aHdb/Myo7a+, Myo7aHdb/Myo7a+ Myo7a4626SB/Myo7a+, and Myo7ash1/Myo7ash1 mice

hearing/vestibular/ear
• apical stereocilia bundles of inner hair cells appeared more disorganized than in Hdb heterozygotes but less than in Hdb homozygotes
• inner hair cell fusion was significantly reduced compared to that seen in Hdb homozygotes but not when compared to Hdb heterozygotes
