Genetic Alterations
ENU mutagenesis created a C>T point mutation in exon 6 of the murine Ccdc62 gene (MGI:2684996) predicting the replacement of the wild-type arginine with a premature stop codon in the highly conserved second coiled-coil domain. Western blot analysis showed the expression of a truncated peptide from this allele and qRT-PCR showed a significant reduction of mRNA expression from the allele in testes.

  • nucleic acid level: c.850C>T
  • amino acid level: p.(Arg284*), p.R284*
Genotype Determination
ES Cell Line
NA
Phenotype
The ENU-induced repro29 mutation is a point mutation in the Ccdc62 (coiled-coil domain containing 62) gene that results in the formation truncated protein. Homozygous males have normal testes size and weight and a normal number of sperm, but are sterile due to deformed sperm. The sperm head is bent and there are outer dense fibers with the head and middle piece enclosed in retained cytoplasm. Almost 100% of sperm are deformed and the number of motile sperm is less than 5% normal. Although a shortened protein of approximately 32 kDa instead of 72 kDa is found in developing spermatids of homozygotes, this truncated protein fails to correctly localize to the developing acrosome, as wild-type protein does, and instead shows a staining pattern of larger cytoplasmic aggregates. Although the morphology of the spermatid nuclei is relatively normal during the Golgi, cap and elongation phases, it becomes condensed in the maturation phase. Heterozygous males and homozygous females have normal fertility and litter size, and homozygous males do mount females resulting in a plug, but fail to impregnate females.

Strain Development
C57BL/6J males were exposed to ENU and subsequently bred to C3HeB/FeJ females. The male offspring were bred to C3HeB/FeJ females and their female offspring were backcrossed to their carrier male father to generate pups that could be homozygous for any ENU-induced mutation. After one further generation of sibling intercrossing sperm was frozen from heterozygous males. Cryo-recovery was done using C57BL/6J oocytes and heterozygous males identified by genotyping were then used for a new sperm freeze. The mutation has been identified as a C to T point mutation that converts an arginine to a stop codon (R284*) in exon 6 of the Ccdc62 (coiled-coil domain containing 62) gene. The repro29 mutation results in the formation of a premature stop codon and truncated protein.

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.

Colony and Husbandry Information

Don't breed sterile homozygous males.

Cryo-recovered strains distributed by the MMRRC at JAX are shipped to the customer from the Pathogen & Opportunistic-Free Animal Room G200 - see https://www.jax.org/jax-mice-and-services/customer-support/customer-service/animal-health/health-status-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 csmmrrc@jax.org.

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 csmmrrc@jax.org 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.

Some MMRRC strains were submitted by the donor as cryopreserved germplasm, and because these strains were not cryopreserved by the MMRRC, we have not assessed the quality, nor genotype, of this material. Our expertise in reviving mice from various qualities of frozen sperm and embryos, using methods like IVF and ICSI, gives us confidence in successful recoveries in most cases. However, due to the uncertain quality of these samples, we'll limit revival attempts to two per order. Additional attempts are available for a fee, on top of standard charges, if requested. It's important to note that some strains may lack the expected mutation, so we can't assure successful order fulfillment until we attempt to revive the strain.

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.
