These congenic genome-tagged mice (GTM) were originally identified to carry a Chromosome 13 segment between markers Mit198 to Mit314 from the DBA/2 strain.
In 2018, a 163 SNP (single nucleotide polymorphism) panel analysis distinguishing between C57BL/6J and DBA/2J was performed on this mouse line. Consistent with previous results, the DBA/2J congenic region on chromosome 13 showed the proximal crossover point between 23.1-33.6 Mbp. However, this analyses extends the most distal end of the DBA/2J region: the most distal markers tested were DBA/2J allele-type (82.2, 85.1, 93.0 and 94.0 Mbp). Additionally, three markers within this region were C57BL/6J allele-type (at 65.3, 65.9 and 66.8 Mbp), flanked by DBA/2J allele-type markers proximally at 61.9 Mbp and distally at 77.8 Mbp. Taken together, this suggests these mice have two DBA/2J congenic regions on chromosome 13: one spanning at least from 33.6-61.9 Mbp and the other spanning at least from 77.8-94.0 Mbp.

Marker-assisted breeding was used to construct a set of overlapping congenic strains called genome-tagged mice (GTM) that span the entire mouse genome. Each member of the panel carries an average of a 23 cM segment (range 8 to 58 cM) from DBA/2J introgressed on to a C57BL/6J background. The segments represent the distal (D), middle (M), and proximal (P) portions of all or most of a given chromosome. GTM are a valuable resource for mapping and confirmation of loci contributing to complex traits. A more detailed explanation of the chromosome intervals are described in Iakoubova et al. 2001 Genomics 74:89 and Davis et al. 2005 Genomics 86:259. Dr. Lusis donated the panel to The Jackson Laboratory in 2004.
Stock No. 005188 is a C57BL/6J congenic strain carrying the middle portion of chromosome 13 from
DBA/2J. The Mit or SNP (rs) markers in the strain name define the
congenic interval.
In
2018, a 163 SNP (single nucleotide polymorphism) panel analysis
distinguishing between C57BL/6J and DBA/2J was performed on this mouse
line. Consistent with previous results, the DBA/2J congenic region on
chromosome 13 showed the proximal crossover point between 23.1-33.6 Mbp.
However, this analyses extends the most distal end of the DBA/2J
region: the most distal markers tested were DBA/2J allele-type (82.2,
85.1, 93.0 and 94.0 Mbp). Additionally, three markers within this region
were C57BL/6J allele-type (at 65.3, 65.9 and 66.8 Mbp), flanked by
DBA/2J allele-type markers proximally at 61.9 Mbp and distally at 77.8
Mbp. Taken together, this suggests these mice have two DBA/2J congenic
regions on chromosome 13: one spanning at least from 33.6-61.9 Mbp and
the other spanning at least from 77.8-94.0 Mbp.
This congenic panel was initiated by a cross of B6D2F1/J females (Stock No. 100006) to C57BL/6J males (Stock No. 000664).
Male progeny at each generation were selected by marker assisted genome scan and were backcrossed to C57BL/6J females to produce the N3-N6 generations. All animals in the panel carry a C57BL/6J Y chromosome. Sibling pairs at the N6 generation were intercrossed to produce homozygotes. A more detailed explanation of the chromosome intervals are described in Iakoubova et al. 2001 Genomics 74:89 and Davis et al. 2005 Genomics 86:259.

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.
