Strain Information

Genetic Alterations

QTL Burly1 was created in the donor's laboratory by introducing a donor chromosomal fragment from 129P3/J (JAX Stock #000690; donor strain) into the genetic background of C57BL/6ByJ (JAX Stock #001139). The donor fragment captures the lean body mass QTL1, Burly1.

Phenotype

Homozygous: The phenotype for this mouse strain is abnormal lean body mass [MP:0003959]. Mice with the Burly1-129 allele have heavier lean body mass than mice with the Burly1-B6 allele.

Hetero/Hemizygous: Burly1 -B6 allele is dominant. Therefore, mice with the one or two Burly1 129 alleles have heavier lean body mass than mice with two Burly B6 alleles.

Cre-excised Phenotype: Undetermined

Strain Development
To map the Burly1 (lean and body fat mass QTL1) QTL on Chr 2, the congenic strain was branched during the production of the consomic strain C57BL/6ByJ-Chr 2129P3/J/MonMmjax (MMRRC:036688). Thus, the initial stages of breeding of this congenic strain and the C57BL/6ByJ-Chr 2129P3/J/MonMmjax consomic (chromosome substitution) strain were identical. As the congenic strain name indicates, we used the 129P3/J strain as a donor and C57BL/6ByJ strain as an inbred partner (host). To eliminate the Y chromosome from the donor strain, we backcrossed F1 females to C57BL/6ByJ males. For the remaining backcross generations (N2 and beyond), male offspring with a non-recombinant Chr 2 derived from the donor strain were identified by genotyping and backcrossed to C57BL/6ByJ females. To accelerate elimination of the donor background genome, we used a "speed consomic" approach, drawing on information from genome scans of the N2 and N3 (948 DNA markers from 19 autosomes and the X chromosome). We used males with a non-recombinant donor chromosome and with the smallest proportion of the donor genome in rest of the chromosomes as founders for the next generation. In subsequent backcrosses (N4-N8), the donor chromosome (Chr 2) was genotyped with a set of 12 SNP markers. We used an N8 male with a recombination of the donor chromosome as a founder of this congenic strain. We intercrossed N8 males and females with donor chromosome (chr2) to produce N8F2 and N8F3. We backcrossed an N8F3 male retaining the Burly1 donor region to C57BL/6ByJ females to produce the N9F3 generation. We genotyped the N9F3, N10F3, N11F3, N12F3 and N13F3 generations (N9F13 and N13F3 were genotyped with 43 SNP markers to identify new recombinants). We intercrossed male and female mice from the N13F3 generation to produce the homozygous N13F4 and N13F5 congenic strain, which included mice with a homozygous donor fragment of Chr 2 from rs27388294 to rs47577392 (150.8 -152.6 Mb).

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.

The donor or their institution limits the distribution to non-profit institutions only.

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.
