Type: Transgene

Genetic Alterations
A lentiviral transgenic approach was used to generate these mice. The Tyro-IRES-sd-loxP-FUGW lentiviral transgene (LV2187) was designed with a mouse tyrosinase minigene (Tyro) followed by an IRES::3xATG::splice-donor::loxP sequence in the FUGW self-inactivating HIV-based lentiviral vector backbone. The Tyro-IRES-sd-loxP replaced the ubiquitin-c promoter, EGFP, and WPRE sequences originally found in the FUGW lentiviral vector. The Tyro minigene is composed of the mouse Tyr enhancer region (623 bp), promoter region (657 bp), and 1566 bp cDNA sequence (including the stop codon); all in antisense orientation relative to the FUGW backbone. The Tyro minigene is followed by an internal ribosome entry site (IRES) ending with ATGs in all three reading frames (3xATG), an artificial splice donor sequence, and a loxP site in this construct. This packaged lentivirus was injected subzonally (under the zona pellucida) into 1 cell stage FVB/N mouse embryos. Expression of the tyrosinase minigene results in melanin synthesis, so founder mice (F0) were identified by inspection for pigmentation. All F0 mice exhibited mosaic pigmentation. Most F0 mice had more than one lentiviral integration site. F0 mice were assigned an OVE number and then bred with FVB/N mice. Pigmented offspring (F1) with different coat colors were designated as subline A, B, C, etc., for each family. F1 mice were bred with FVB/N mice. F2 mice with different coat colors were designated as sublines A-1, A-2, etc., or B-1, B-2, etc. Breeding with FVB/N mice was continued until litters with only one or two different coat colors were obtained. Mice with identical coat colors were then inbred and assessed for the presence or absence of viable homozygotes. Hemizygous mice of line OVE 2364E-2a2 exhibit a light grey coat color. Using inverse PCR analysis, the lentiviral integration site was identified in intron 8 of the Fanconi anemia E gene (Fance) on chromosome 17. The 3'-LTR is linked to the (+) strand of DNA at position 28,458,210 bp [NCB137/mm9; 3'-28,458,210(+)].
Genotype Determination

Strain Description

Phenotype

The phenotype of the Fance mutants resembles the phenotype of other Fanconi anemia mutations in mice.
Homozygous: Homozygous females are sterile. Homozygous males are subfertile.

Hemizygous: Undetermined.

MMRRC Genetic QC

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 csmmrrc@jax.org. Older strains may not have this information.

Order Request Information

Availability Level

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 csmmrrc@jax.org for more information.

Conditions of Distribution

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.

Fees

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.
