Related Genotype: a/aImportant Note
This strain is homozygous for Cdh23ahl, the age related hearing loss 1 mutation, which on this background results in progressive hearing loss with onset prior to 3 months of age.Strain Description
Although C57BLKS/J is estimated to have more than 70% of its genome derived from C57BL/6J, these strains are phenotypically distinct. Diet-induced atherosclerotic lesions are much more severe in C57BLKS/J than in C57BL/6J or many other inbred strains. Compared with a panel of inbred strains, C57BLKS/J was found to have low total cholesterol and low HDL cholesterol when fed a normal diet and high total cholesterol and HDL cholesterol in an atherogenic diet. Paigen et al. found high levels of plasma bile salts in C57BLKS/J females after 8 weeks on an atherogenic diet. The mutations diabetes (Leprdb) and obese (Lepob) each express a much more severe phenotype on the C57BLKS/J background than on the C57BL/6J background. The Cpefat mutation causes severe obesity, hyperinsulinemia, and hyperglycemia on the C57BLKS/J background rather than the hyperinsulinemia, and mild obesity without hyperglycemia found on the HRS/J background. In a comparative study of 43 inbred strains, Barker and Peters found that C57BLKS/J had a relatively high percentage of reticulocytes per total number of erythrocytes, high white blood cell count per volume, with a high percentage of lymphocytes and basophils and a low percentage of neutrophils per total number of leukocytes. C57BLKS/J mice exhibit age related hearing loss by 3 months of age.Strain Development
In October, 1947, while at The Sloan-kettering Institute, Dr. N. Kaliss obtained a C57BL/6J male from The Jackson Laboratory and obtained a female, which was reported to be one generation removed from the male, from a pen-bred colony of C57BL/6J of Dr. J. J. Biesele. Dr. Kaliss bred these together and maintained an inbreeding line of what he thought were C57BL/6J and brought them back with him to The Jackson Laboratory in 1948. He found that with continued inbreeding this strain rejected the C57BL/6-derived sarcoma E0771. It was subsequently determined that this strain had a genetic contamination untraced in origin. Rather than the H2b of C57BL/6J, this strain was found homozygous for the H2d haplotype found also in DBA/2J. Polymorphisms have been assessed to characterize this contamination and Mao et al., following on work of Naggert et al. and Slingsby et al., reported finding that the C57BLKS/J genome derived from 71% C57BL/6J, 25% DBA/2J, and 4% from a combination of C57BL/10J, a 129 source, and possibly some other undefined source. Clusters of 129-like alleles were found on Chr 4 and 15, C57BL/10-like alleles were found on Chr 11 and elsewhere in the genome, and additional unique alleles were also identified.

| Molecular Note | Genetic complementation tests have shown allelism between the mdfw (modifier of deaf waddler) locus and the ahl locus. Further analysis has identified an association between ahl and a G to A transition at nucleotide position 753 of Cdh23. This hypomorphic allele causes in frame skipping of exon 7 and reduced message stability. Twenty-seven strains classified with ahl and carrying the 753A allele include: CD1, RBF/DnJ, PL/J, AKR/J, RF/J, BALB/cBy, A/WySnJ, P/J, SENCARA/PtJ, DBA/1J, ALS/LtJ, C58/J, C57BLKS/J, 129/ReJ, C57BR/cd, SKH2/J, BUB/Bn, MA/MyJ, LP/J, 129/ScJ, NOR/LtJ, A/J, C57BL/6, NOD/LyJ, DBA/2J, ALR/LtJ, C57L/J. Strains classified with ahl that DO NOT carry this mutation include: C3H/HeSnJ, I/LnJ,YBR/Ei, MRL/MpJ. [J:86905] | ||

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.Ordering and Purchasing Information
