Strain Information

Former Names B6CBA-Mitfmi-rw    (Changed: 15-DEC-04 ) Type Coisogenic; Mutant Strain; Spontaneous Mutation; Additional information on Genetically Engineered Mutant Mice. Species laboratory mouse Generation F155+32N1F3N1p

Description
Mutations at the Mitf locus affect eye size, pigmentation, and the capacity for secondary bone resorption. Mice homozygous for the red-eyed white spontaneous mutation Mitf^mi-rw have some pigmentation around the neck and have small red eyes.

Development
The red-eyed white recessive mutation (Mitf^Mi-rw) arose spontaneously in the CBA/J strain.

Genes & Alleles

Gene & Allele Information

Allele Symbol		Mitfmi-rw
Allele Name		red eyed white
Allele Type		Spontaneous
Strain of Origin		CBA/J
Gene Symbol and Name		Mitf, microphthalmia-associated transcription factor
Chromosome		6
Gene Common Name(s)		MI; WS2A; bHLHe32; black eyed white; bw; mi; microphthalmia; vit; vitiligo; wh;
General Note		Mitfmi-rw, red-eyed white, recessive. This mutation arose spontaneously in the CBA/J strain. Homozygotes have some pigmentation around the neck and have small red eyes. Mitfmi-rw/Mitfmi mice are all white with small or absent eyes; Mitfmi-rw/Mitfmi-sp, fully pigmented except for a white belly spot; and Mitfmi-rw/MitfMi-wh mostly white with tan spots and red eyes (J:13661). There is a deletion of upstream sequences in the Mitfmi-rw mutation (J:21366).
Molecular Note		This allele contains a large genomic deletion that begins approximately 6kb upstream of the melanocyte-specific 5' end and includes the heart-specific 5' end. [MGI Ref ID J:21366]

Supply Details

Standard Supply

Repository-Cryopreserved. Must Be Recovered. Please refer to pricing and supply notes for further information.

Supply Notes

Cryorecovery - Standard. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 or 1-207-288-5845. Genomic DNA is available for this strain from the Mouse DNA Resource.

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.
