Important Note

This strain is homozygous for fz, Mlph^ln, and Ednrb^s, and is segregating for Cdh23^v.

Detailed Description

This strain was originally used as a linkage stock for gene mapping. It is homozygous for several visible recessive mutations all located on different chromosomes including nonagouti (a), fuzzy (fz), leaden (Mlph^ln), and piebald (Ednrb^s) and is segregating for the neurological mutation, waltzer (Cdh23^v). Homozygous waltzer mice show the circling, head-tossing, deafness, and hyperactivity typical of the circling mutants. Abnormalities of the inner ear include degeneration of the organ of Corti, spiral ganglion, stria vascularis, and saccular macula. Homozygous piebald mice show irregular white spotting, the amount of which is greatly influenced by minor modifying genes. Homozygous piebald mice have dark eyes. The white areas of the coat are completely lacking in melanocytes and there is a reduction in the number of melanocytes in the choroid layer of the eye.

Development

The waltzing mutation came from the Japanese mouse fanciers and was received by George Snell at The Jackson Laboratory from Ludwin in 1947 when the stock was homozygous for nonagouti, leaden, waved 1, and piebald. This stock was crossed once to C57BL/10 and non-sibling mated for approximately 22 generations after which it was crossed to a C57BL/10 stock bearing fuzzy and jittery. The fuzzy and waved 1 mutations were selectively bred out of the stock. Sibling inbreeding of this stock began in approximately 1960. In 1983 this stock was at generation F47 and waltzer heterozygous females were bred with homozygous males to generate embryos for cryopreservation.

Genetics

Sgk3^fz

Allele Symbol: Sgk3^fz

Allele Name	fuzzy
Allele Type	Spontaneous
Allele Synonym(s)
Gene Symbol and Name	Sgk3, serum/glucocorticoid regulated kinase 3
Gene Synonym(s)
Strain of Origin	CFW stock
Chromosome	1
Molecular Note	This mutation comprises insertion of a single adenine following nucleotide 579 of the cDNA sequence, in a region encoded by exon 10 of the gene, that causes a shift in the amino acid reading frame and premature termination of protein translation following leucine 192 (Leu192Ter), which resides in the serine/threonine kinase domain.

Ednrb^s

Allele Symbol: Ednrb^s

Allele Name	piebald
Allele Type	Spontaneous
Allele Synonym(s)	pied spotting; s
Gene Symbol and Name	Ednrb, endothelin receptor type B
Gene Synonym(s)
Strain of Origin	old mutant of the mouse fancy
Chromosome	14
General Note	Also called piebald spotting. This is a very old mutation of the mouse fancy, and was described in the scientific literature as early as 1920 (J23183). Some piebalds in existing stocks may be of independent origin.
Molecular Note	This mutation is allelic to a targeted mutation for this gene. Homozygous mice produce approximately 25% of the normal levels of transcript from this allele. RT-PCR analysis demonstrated that no alterations in the coding sequence would result in any alteration of the amino acid sequence. A 5.5 kb retrotransposon-like element is found in intron 1. About 75% of the mRNA produced is an aberrant 6.5 kb form lacking exons 2-6 but containing exon 1. The remaining 25% of the mRNA formed is of normal, 4.4 kb, size.

Cdh23^v

Allele Symbol: Cdh23^v

Allele Name	waltzer
Allele Type	Spontaneous
Allele Synonym(s)	v
Gene Symbol and Name	Cdh23, cadherin 23 (otocadherin)
Gene Synonym(s)
Strain of Origin	old mutant of the mouse fancy
Chromosome	10
General Note	Viability and breeding ability are somewhat less than normal. Homozygotes show the typical circling, head-tossing, deafness, and hyperactivity of the circling mutants. Most of them are deaf from the beginning. Abnormalities of the inner ear include degeneration of the organ of Corti, spiral ganglion, stria vascularis, and saccular macula. Double heterozygotes with shaker-1 (Cdh23^v/+ Myo7^ash1/+) are deaf beginning at 3 to 6 months. They 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 (J:13130)(J:15164).
Molecular Note	A single G nucleotide insertion at coding nucleotide 834 causes a frameshift and premature termination of the encoded protein.

Mlph^ln

Allele Symbol: Mlph^ln

Allele Name	leaden
Allele Type	Spontaneous
Allele Synonym(s)	ln
Gene Symbol and Name	Mlph, melanophilin
Gene Synonym(s)
Strain of Origin	C57BR
Chromosome	1
Molecular Note	This allele has a C-to-T transition at mRNA nucleotide position 266. This introduces a stop codon at arginine codon 31 (p.R31*) in the sequence of the normally spliced transcript and it also creates a new G-GT splice donor site in exon 2. Use of this alternative splice site yields a transcript with an in-frame 21 base pair deletion that deletes 7 amino acids from the translated protein. Northern blots failed to detect this size difference and did not find any change from normal in transcript expression level. Sequence analysis failed to detect any wild-type transcripts.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
