Genetic Alterations

This congenic strain has been created in the donor's laboratory by introducing a donor chromosomal fragment from the 129P3/J (JAX Strain #000690) inbred strain into the genetic background of the C57BL/6ByJ (JAX Strain #001139) inbred partner strain. This donor fragment captures the alcohol preference 7 QTL, Ap7q.

Genotype Determination
  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • Phenotype

    Homozygous: Mice with the Ap7q129P3/J (MGI:2668896) allele consume more 10% ethanol than mice with the Ap7qC57BL/6ByJ (MGI:2668895) allele.

    Hetero/Hemizygous: Ap7qC57BL/6ByJ (MGI:2668895) is dominant. Therefore, mice with one or two Ap7q129P3/J (MGI:2668896) alleles drink more ethanol than mice with two Ap7qC57BL/6ByJ alleles.

    Strain Development
    This is a congenic strain produced to map the Ap7q (Alcohol preference 7 QTL) locus on Chr 7. This congenic strain was branched out during production of the consomic strain C57BL/6ByJ-Chr 7129P3/J/MonMmjax (MMRRC:036689). Therefore, initial stages of development of this congenic strain and the C57BL/6ByJ-Chr 7129P3/J/MonMmjax consomic strain were identical. 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, F1 females were backcrossed to males from the C57BL/6ByJ host strain. To facilitate the elimination of the donor 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 with the smallest proportion of the donor genome in the rest of the chromosomes were used as founders of the next generation. An N3 with a donor fragment-covered Ap7q region (35.3 to 53.7 Mb) was used as a founder of these congenic strains. In subsequent backcrosses, the donor fragment region was genotyped with a set of DNA markers. N8 mice produced by backcrossing this founder and its offspring to C57BL/6ByJ females were intercrossed to produce the N9F2 generation. N9F2 mice homozygous for a donor fragment of Chr 7 defined by rs31912252 [the donor fragment not extending past the proximal marker rs31766653 (36.4 Mb) and the distal D7Mit52 (40.1 Mb)] were used as founders for this strain.

    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 mmrrc@med.unc.edu 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.
