alleles, and
All mutations/alleles(6) : Targeted(6)
Incidental mutations (data from APF )
Mice homozygous for one targeted mutation are viable and fertile but display progressive hearing loss, with severe degeneration of the auditory hair cells and loss of the endocochlear potential. Mice homozygous for a second allele display normal hearing.
