Other Names   : Charlie Chaplin, Skam10Jus, C3;B6-Twist1Ska10/Mmcd

Gene Information

(provided by MGI)
Allele Symbol: Twist1Ska10
Name: skeletal/axial 10
Chromosome: 12
Alteration at locus: Chemically Induced
Gene Symbol: Twist1
Name: twist basic helix-loop-helix transcription factor 1
Chromosome: 12
Alteration at locus: Chemically Induced
Genetic Alterations:
This phenotypic mutant was identified in an ENU mutagenesis screen at the Baylor College of Medicine. Genomic sequencing revealed a T-C base-pair change in that resulted in a Ser192Pro amino acid substitution in the Twist box of the encoded protein. A mutant protein is expressed from this allele, but in an immunoprecipitation assay, CC mutant protein interacted poorly with Runx2 compared to the wild-type protein.

Genotype Determination:

    ES Cell Line: Not applicable

    Phenotype:

    Homozygous: Lethal
    Heterozygous: Preaxial polydactyly. Affected animals have 6-7 digits on hind feet. In some cases both feet are affected. Extra digits will sometimes curl towards the foot to form a claw like digit.

    Mammalian Phenotype Terms:
    Allelic Composition: Twist1Ska10/Twist1Ska10 (Genetic Background: C57BL/6J-Twist1Ska10 )

    Allelic Composition: Twist1Ska10/Twist1+ (Genetic Background: C57BL/6J-Twist1Ska10 )

    Allelic Composition: Twist1Ska10/Twist1+ (Genetic Background: involves: C57BL/6J )

    Strain of Origin: C57BL/6

    Strain genetic background: C3H;B6

    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.

    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 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.

    2 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.

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