Genetic Alterations
The Kif7 gene consists of 20 exons, with the start codon located in exon 2 (NCBI accession XM_133575.5). Coding exon 2 was targeted by homologous recombination.
Genotype Determination
ES Cell Line
Lexicon cell line derived from 129S5/SvEvBrd
Phenotype
Genetic data showed homozygous mutant animals were not recovered with Mendelian ratios suggesting prenatal or postnatal lethality.
Refer to phenotypic data for the affects of this mutation on the F2 heterozygous mice.
The phenotype of this strain may be different due to genetic background effects.

Strain Development
Targeted or gene trap mutations are generated in strain 129/SvEvBrd-derived embryonic stem (ES) cells. The chimeric mice are bred to C57BL/6-Tyrc-Brd albino mice albino mice to generate F1 heterozygous animals. These progeny are intercrossed to generate F2 wild type, heterozygous, and homozygous mutant progeny. On rare occasions, for example when very few F1 mice are obtained from the chimera, F1 heterozygous mice are crossed to 129/SvEvBrd x C57BL/6 hybrid mice to yield additional heterozygous animals for the intercross to generate the F2 mice.

Mice are archived at the backcross generation N7. Recovery will be performed using C57BL/6NCrl donors unless otherwise requested.
Suggested Control Mice
Wild-type littermates or C57BL/6NCrl mice
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@ucdavis.edu. Older strains may not have this information.

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@ucdavis.edu for more information.

Distribution of this strain requires execution of the Genentech Lexicon agreement. A link to this form will be provided via email when an order is submitted; the PDF form should be downloaded or the email forwarded to the appropriate institutional representative for completion following directions in the document.

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.
