Imbalance behaviors of Oc90 null mice in comparison with some otoconia mutants

Abnormal/total WT Oc90 Null Otop1tlt Nox3het
Head-tilting (2–3 wk) 0/64 37/161*** 10/12*** 5/8***
Head-tilting (adult) 0/12 1/15 7/10*** 7/9***
Air-righting (P9–10) 0/10 10/17** 9/9*** 10/11***
Reaching (2–3 wk) 0/10 1/6 12/12*** 8/8***
Reaching (adult) 0/12 0/15 7/10*** 6/9**

The number of mice showing imbalance behaviors is shown as the numerator and the total number of mice tested as the denominator. P values were obtained using chi-square analysis. Adult ages tested were 2–8 month homozygous mutants or wt. Age-matched C57 mice were all normal and are not listed in the table.
