Description

These congenic genome-tagged mice carry a Chromosome 13 segment between markers Mit79 to Mit198 from the DBA/2 strain.

Detailed description

This C57BL/6J congenic carries the proximal portion of chromosome 13 from DBA/2J. The Mit or SNP (rs) markers in the strain name define the congenic interval.

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. (Iakoubova OA, et. al., 2001) GTM are a valuable resource for mapping and confirmation of loci contributing to complex traits.

The Jackson Laboratory is working with Dr. Lusis' group to import and make available additional strains in the panel.

Development

This congenic panel was initiated by a cross of B6D2F1/J (Stock #100006) females to C57BL/6J males. 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. Iakoubova OA, et. al. provides a more detailed explanation of the chromosome intervals. Dr. Lusis donated the panel to The Jackson Laboratory in 2004.
