Genetic Alterations
This strain represents one of a set of 7 consomic strains in which progenitor inbred strains C57BL/6ByJ and 129P3/J were used to construct reciprocal chromosome substitution strains (CSSs) for Chr 1, 2, 7 and 9 using a "speed consomics" approach. In this strain, chromosome 7 was moved from donor strain C57BL/6ByJ to host strain, 129P3/J.
Genotype Determination
Phenotype
The 129P3/J and C57BL/6ByJ progenitor inbred strains differ in taste responses, ingestive behavior, alcohol consumption, body size, adiposity, and other traits. Genome scans of crosses between these strains have detected QTLs for these phenotypes that cluster on Chr 1, 2, 7 and 9 (Adip2; Adip3, Adip5, Ap7q, Bwq5, Bwq6, Nattq1, Nattq2, Sucq).

Strain Development
Our breeding scheme was designed to eliminate Y chromosome from the donor strain. The 129P3/J and C57BL/6ByJ progenitor inbred strains were crossed and F1 females were backcrossed to males from a host strain, 129P3/J. Male offspring with a non-recombinant chromosome derived from the donor strain were identified in each backcross generation by genotyping and were backcrossed to females from the host strain, 129P3/J. To facilitate elimination of the donor, C57BL/6ByJ genome in non-target chromosomes using a "speed consomic" approach, we conducted genome scans of the N2 and N3 backcross generations (948 SNPs covering 19 autosomes and the X chromosome were genotyped to identify optimal breeders). Males with a non-recombinant donor chromosome and the smallest proportion of the donor genome in rest of the chromosomes were used as founders of the next generation. In subsequent backcrosses, donor chromosomes (1, 2, 7, 9) were genotyped with sets of SNP markers. We used the most centromeric and the most telomeric polymorphic markers available. To prevent loss of donor chromosome fragments due to double-crossovers, we calculated the cross-specific genetic recombination distances between markers and selected internal markers spaced no more than 10 cM. At the N7 backcross generation, males and females with the non-recombinant donor chromosome were intercrossed. Progeny of this intercross that are homozygous for the donor, C57BL/6ByJ chromosome was used to propagate the consomic strains.

In 2013, a 154 SNP (single nucleotide polymorphism) panel analysis covering all 19 chromosomes and the X chromosome was performed at The Jackson Laboratory. All markers on Chr 7 are fixed for the C57BL/6 allele type. The remaining markers are fixed for 129P3/J with the exception of 3 markers on Chr 8 and 1 marker on Chr 10 that tested as heterozygous for C57BL/6 and 129P3/J.

Order Request Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Cryopreserved material may be available upon request, please inquire to csmmrrc@jax.org for more information.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
