All mutations/alleles(4) : Gene trapped(1) Targeted(3)
Incidental mutations (data from Mutagenetix , APF )
Mice homozygous for a knock-out allele display progressive retinal photoreceptor degeneration along with significantly reduced a- and b-wave amplitudes, and a moderate but nonprogressive high-frequency hearing loss associated with widespread loss of outer hair cells in the basal turn of the cochlea.
