Type Mutant Stock; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Species laboratory mouse Generation ?+N1p (15-JAN-06)
Generation DefinitionsDonating Investigator Roger H. Reeves, Johns Hopkins Univ. Schl. Med Description
These mice are monosomic for the mouse chromosome segment orthologous to the human chromosome 21 Down syndrome critical region (DSCR). The deleted segment contains mouse orthologs of 33 conserved and minimally conserved genes in the human DSCR. The borders of the deletion are defined by the carbonyl reductase 1 (Cbr1) gene and a site adjacent to the myxovirus (influenza virus) resistance 2 (Mx2) locus. Monosomic mice are viable, fertile and are significantly smaller than wildtype (euploid) littermates from birth to adulthood. This mouse may be useful in studies of Down syndrome and further exploring the ploidy of the DSCR segment of mouse Chr 16.Development
A targeting vector containing a 3' portion of a neomycin resistance gene, a loxP site, and a hygromycin resistance gene at the (Cbr1) locus at the proximal end of the DSCR on MMU16 was electroporated into 129S6/SvEv-derived MC1 embryonic stem (ES) cells. Correctly targeted ES cells were then electroporated with a second targeting vector designed to orient a puromycin resistance gene, a loxP site, and a 5' portion of a neomycin resistance gene adjacent to the (Mx2) locus at the distal end of MMU16. Next, a CAGGS-cre expression vector was electroporated into ES cells harboring both targeted mutations. In ES cells where each construct inserted in trans on homologous chromosomes, recombination between the loxP sites resulted in mice with a duplication of the MMU16 region between the loxP sites on one homologous chromosome and interstitial deletion of the MMU16 region between the loxP sites on the other homologous chromosome. Heterozygous ES cells were injected into blastocysts and then transferred to surrogate mothers. F1 progeny of chimeric mice were bred to (C57BL/6J x C3H/HeJ)Fn to produce mice with segmental monosomy of MMU16 (Stock# 5654 -Del(16Cbr1-ORF9)1Rhr) or segmental trisomy (see Stock# 5383 -Dp(16Cbr1-ORF9)1Rhr). Monosomic mice were crossed with (C57BL/6J x C3H/HeJ)F1 for 4 generationsbefore arriving at The Jackson Laboratory. Upon arrival, this mutant strain has been maintained by breeding with B6C3F1/J.

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 Information
