Strain Description
Mice homozygous for the waltzer 2J spontaneous mutation (Cdh23v-2J) show the circling, head-tossing, deafness, and hyperactivity typical of the circling mutants. Homozygous mutant mice are very similar to the other waltzer mutants (Cdh23v and Cdh23v-J). Most homozygotes are deaf from birth. Abnormalities of the inner ear include degeneration of the organ of Corti, spiral ganglion, stria vascularis, and saccular macula. Double heterozygotes with shaker-1 (v/+ Myo7ash1/+) are deaf beginning at 3 to 6 months. Double heterozygotes have changes similar to those of the homozygotes in the organ of Corti, stria vascularis, and spiral ganglion, but less severe and with much later onset. Viability and breeding ability are somewhat reduced.

| Molecular Note |
A G-to-A transition at the first nucleotide of intron 32 alters the wild type donor splice site. RT-PCR analysis demonstrated that aberrant transcripts were produced from this allele, and all of these were predicted to introduce a premature stop codon. [MGI Ref ID J:66698]

The Jackson Laboratory's Genotype Promise
The Jackson Laboratory has rigorous genetic quality control and mutant gene
genotyping programs to ensure the genetic background of JAX
® Mice strains as
well as the genotypes of strains with identified molecular mutations.
JAX
® Mice strains are only made available to researchers after meeting our
standards. However, the phenotype of each strain may not be fully
characterized and/or captured in the strain data sheets.
Therefore, we
cannot guarantee a strain's phenotype will meet all expectations. To
ensure that JAX
® Mice will meet the needs of individual research projects
or when requesting a strain that is new to your research, we suggest ordering
and performing tests on a small number of mice to determine suitability for
your particular project.
