Type: Gene
Species: Mouse
Chromosome: 9
Alteration at locus: Knock-In
NCBI: 26432
HGNC: HGNC:9082
Homologene: 22681
Genetic Alterations
The targeting construct introduced an FRT-flanked neomycin resistance cassette with a 5' loxP site upstream of exon 13, a frameshift mutation into exon 13a, and a second loxP site downstream of exon 14. Flp-mediated recombination removed the selection cassette. This models a variant identified in two unrelated individuals with Bruck syndrome.
ES Cell Line
Cyagen B6N derived from C57BL/6NCrl (unpublished Cyagen, in-house)
Phenotype
  • Homozygous mice: recapitulate the Bruck syndrome phenotypes including exhibiting contractures in all limbs, smaller body size and weight, and altered cervical spine curvature.
    • variability in embryonic lethality: ~1/3 of those expected to survive to E18.5
    • none survive after birth
    • survive longer than the global Plod2 knockout (lethal at E10.5)
  • Heterozygous mice: display no obvious phenotype and no sex differences

Strain GQC Summary
Gene Specific Genotyping:

To request gene-specific and other genotyping services for a strain, please contact the distribution MMRRC Center for more information.

Background Genetic Quality:

The MMRRC has developed a Genetic Quality Control pipeline using the MiniMUGA array to provide additional information to identify and validate genetic backgrounds of MMRRC strains. For more information on whether genetic background data is available, please contact MMRRC_GeneticQC@med.unc.edu. Note: that MiniMUGA genetic background data is not available on all strains, but can be ordered if desired.

Suggested Control Mice
Littermates of all relevant genotypes.
  • Internal/Organ
  • Models for Human Disease

Strain Development
PCR using BAC clones RP23-135C4 or RP23-122O17 were used to create homology arms for a targeting construct including the modeled duplication (NM_001142916.1: c1796dupC; p.Val523Cysfs∗7). Cyagen B6N (C57BL/6NCrl) embryonic stem cells were used for gene targeting and blastocyst microinjection followed by chimera production. Mice with the generated frameshift allele (Plod2fs) were bred to heterozygosity to maintain the colony. As no homozygous mice survived past birth and WT C57BL/6 mice are known to have low bone density, heterozygous mice were bred with C3H/HeJ and backcrossed for more than 10 generations.


Disclaimer: If MMRRC Strain Genetic Quality Control (GQC; based on MiniMUGA genotyping and analysis) has been completed for this strain, the information might differ from the genetic background information provided by the submitter. MiniMUGA genetic analysis is done on a strain’s tissue samples taken when archived by or ordered from the assigned MMRRC Center.

Order 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@ucdavis.edu for more information.

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

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.

Units Notes
072097-UCD-RESUS Litter recovered from cryo-archive $5,892.91 / Non-Profit Litter Recovered litter4; additional fees for any special requests.
Cryopreserved material may be available upon request, please inquire to mmrrc@ucdavis.edu for more information.

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.
