Strain Information

Alox12bmmy
Name: arachidonate 12-lipoxygenase, 12R type; mummy
Synonyms: 12R-LOX-, Alox12bmmy-Bei
Type: Allele
Species: Mus musculus (mouse)
Chromosome: 11
Alteration at locus: Chemically Induced
Alox12b
Name: arachidonate 12-lipoxygenase, 12R type
Synonyms: Aloxe2, e-LOX2, 12R-LOX
Type: Gene
Species: Mouse
Chromosome: 11
Alteration at locus: Chemically Induced
NCBI: 11686
HGNC: HGNC:430
Homologene: 884
Genetic Alterations
G to A single base pair change in exon 14 of the Alox12b gene. The mutation introduces a nonsense codon into the C-terminal lipoxygenase catalytic domain (W633X) and truncates the protein by 68 amino acids.
Genotype Determination
  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • Phenotype
    Homozygous: Affected mice are born with red, shiny skin that rapidly desiccates and becomes scaly. The mutation causes lethality within 24 hours of birth, due to a defect in the water barrier. Histological analysis of newborn epidermis demonstrates a thickened, compressed stratum corneum in the affected mice in contrast to the normal basket-weave corneum layers in unaffected littermates.

    Heterozygous: Same as wild-type.

    MMRRC Genetic QC Summary
    The MMRRC Centers have developed a genetic QC pipeline using MiniMUGA array genotyping to provide additional information on strain backgrounds for MMRRC congenic and inbred strains. For more information on when data may be available, or to request genotyping for a strain of interest, please contact mmrrc@med.unc.edu. Older strains may not have this information.

    Colony and Husbandry Information

    Colony Surveillance Program and Current Health Reports

    Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email mmrrc_health@med.unc.edu.

    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.

    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.
