Genetic Alterations
Exon 2 ENSMUSE00000513998 was constitutively deleted from the 5 UTR through the 3 UTR from Cdc42ep3 gene ENSMUST00000068958.7 using CRISPR Cas9 gene editing technology in mouse zygotes.
Genotype Determination
ES Cell Line
MeSH Terms
    Strain Development
    CRISPR guide(s) and Cas9 protein were microinjected or electroporated into C57BL/6NCrl zygotes and progeny were screened for the desired mutation. Founders were mated to C57BL/6NCrl breeders, and derived N1 progeny were identified by PCR and/or sequencing. N1 were then mated again to C57BL/6NCrl breeders, to generate N2 mice, identified by PCR and/or sequencing. N2 heterozygous mutant mice were mated for production of phenotyping cohorts, and N2 or N2F1 mice were used for cryopreservation purposes.
    Suggested Control Mice
    C57BL/6NCrl or wild-type from colony

    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 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 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.
