Kit mice possess pleiotropic defects in pigment-forming cells, germ cells, RBC's and mast cells. In addition, they exhibit impaired resistance to parasitic infection and an intrinsic progenitor cell defect. The lack of germ cells in homozygous mutant mice leads to the development of some ovarian tumors (mesotheliomas and granulosa cell), associated with an overproduction of pituitary gonadotropic hormone. Kit mice generally have a well-defined belly spot with sharp edges and a very variable amount of white in the dorsal coat.Read More +
This strain is homozygous for the retinal degeneration allele Pde6brd1.
Kit mice possess pleiotropic defects in pigment-forming cells, germ cells, RBC's and mast cells.

The lack of germ cells in homozygous mutant mice leads to the development of some ovarian tumors (mesotheliomas and granulosa cell), associated with an overproduction of pituitary gonadotropic hormone.
Mice carrying the KitW mutation were sent from Dr. S. J. Holman and Dr. Salome Waelsch to Elizabeth Russell at The Jackson Laboratory in the late 1940?s. Female #168 was bred with male #169 to begin the generation of inbred lines segregating for KitW and the resulting inbred lines were selected for frequency and longevity of homozygotes. The lines were maintained by full sibling inbreeding and line WB separated from WC at generation F8. Prior to F25 homozygotes on the WB background showed an average lifespan of 10.6 days. Additionally, the mean age of first litter at that time, 75 days, was earlier than that of WC, which was 92 days of age (Russell and McFarland, 1966). In 1960 WB/Re reached generation F36, in 1965 F56, in 1975 F97, in 1986 F126, in 1992 F138, and in 2010 F191. Embryos were cryopreserved in 1987.

|Strain of Origin||old mutant of the mouse fancy|
|General Note||This is an old mutant of the mouse fancy. KitW mutants are a potential model for human inherited pure red cell anemia, called Diamond-Blackfan anemia (OMIM 205900), but mouse mutants do not respond to corticosteroid treatment as do human patients. Thus, the mechanism of anemia causation in the two conditions must be different (J:14286).|
|Molecular Note||A guanosine to adenosine substitution at the first nucleotide at the 5' boundary of the intron following the transmembrane exon results in two different aberrantly spliced transcripts putatively expressed in a tissue specific manner. A deletion of 107 bp was found in transcripts from mast cells of mutant mice. A deletion of 234 was found in transcripts from brain or bone marrow cells. The GT to AT point mutation probably disrupted a splice donor site, thereby causing exon skipping. The 107 bp deletion could have resulted from skipping of a transmembrane region exon and the 234 bp deletion from skipping 3 exons. The 107 bp deletion would generate a stop codon 12 bp downstream because of a frame shift, whereas the larger deletion would still be in frame. Northern blot analysis indicated that mast cells from mutants have only 31-37% of the transcripts as mast cells derived from normal bone marrow, suggesting that the mutation may reduce efficiency and authenticity of transcription and splicing.|

|Strain of Origin||various|
|General Note||The following inbred strains are known to be homozygous for Pde6b |
|Molecular Note||Two mutations have been identified in rd1 mice. A murine leukimia virus (Xmv-28) insertion in reverse orientation in intron 1 is found in all mouse strains with the rd1 phenotype. Further, a nonsense mutation (C to A transversion) in codon 347 that results in a truncation eliminating more than half of the predicted encoded protein, including the catalytic domain has also been identified in all rd1 strains of mice. A specific degradation of mutant transcript during or after pre-mRNA splicing is suggested.|
Wildtype mice from this colony frequently show small belly spots on an otherwise non-diluted black background. Attempts to breed away from this phenotype can reduce the incidence, but can not fully eliminate it.

The average number of mice provided from recovery of our cryopreserved strains is 10. The total number of animals provided,
their gender and genotype will vary. We will fulfill your order by providing at least two pair of mice, at least one animal of
each pair carrying the mutation of interest. Please inquire if larger numbers of animals with specific genotype and genders
are needed. Animals typically ship between 10 and 14 weeks from the date of your order. If a second cryorecovery is needed in
order to provide the minimum number of animals, animals will ship within 25 weeks.
The genotypes of animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description. Please inquire about possible genotypes which will be recovered for this specific strain. The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.
Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.
