Combined cochleo-saccular and neuroepithelial abnormalities in the Varitint-waddler-J (VaJ) mouse.

Hearing loss in Varitint-waddler-J (VaJ) mice is of mixed origin with both cochleo-saccular and neuroepithelial components. Both VaJ/VaJ and VaJ/+ mutants show impaired cochlear function, but the homozygotes are more severely affected than heterozygotes. Neither group have any detectable compound action potential. Cochlear microphonics are only seen in half… CONTINUE READING
