TThis congenic strain carries the H51 minor histocompatibility allele from C3HeB/FeJ (Stock No. 000658) along with the pale-ear mutation (Hsp1ep) that arose on C3HeB/FeJ.

The mutation pale ears (ep) arose spontaneously in strain C3HeB/FeJ at the Jackson Laboratory in 1957. This mutation was maintained on this background by sibling inbreeding with forced heterozygosis by Dr. E. L. Green who subsequently backcrossed the mutation onto C57BL/6J, reaching generation N15 in 1968, and N20F18 in 1974. In 1972 Dr. Don Bailey reported finding numerous C57BL/6J congenic lines with marker genes not to be isocongenic with C57BL/6J by the usual test cross method. One of these histocompatibility loci was temporarily called H(ep) and was located about 16 units from ep (Bailey and Bunker, 1972). This temporary H(ep) locus was likely H51. Dr. Bailey received this strain at generation N20F3 and outcrossed once to C57BL/6By before again maintaining by sibling inbreeding. This strain was cryopreserved in 1979 by mating wildtype (+/+) females with homozygous males at generation B6JN20F3B6ByN1F19.

General Note | Genbank ID for mutant allele: AF003867 |
Molecular Note | The underlying mutation responsible for the phenotype in the pale ear mouse was identified as an insertion of an intracisternal A particle in a protein coding- 3' exon of the Hps1 gene. Northern analysis demonstrated qualitative differences in mRNA between wild-type and homozygous mutant animals. |

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.
