Strain Information

CrygdL23
Name: crystallin, gamma D; L23
Synonyms: gamma D (V76), Crygdm1Btlr
Type: Allele
Species: Mus musculus (mouse)
Chromosome: 1
Alteration at locus: Chemically Induced
Crygd
Name: crystallin, gamma D
Synonyms: DGcry-1, Cryg-1, Aey4
Type: Gene
Species: Mouse
Chromosome: 1
Alteration at locus: Chemically Induced
NCBI: 12967
HGNC: HGNC:2411
Homologene: 36213
Genetic Alterations
ENU-mutagenesis resulting in a T to A transversion at position 263 of the Crygd gene, in exon 2 of 3 total exons. Corresponds to the missense error V76D in the polypeptide chain.
Genotype Determination
Phenotype
Homozygous: homozygous mice have severely deformed lenses that undergo posterior rupture. Lenses contain vacuoles and retain fiber cell nuclei. Abnormal γ-crystallin aggregates are present in the nuclei of homozygous lens fiber cells and total levels of water-soluble γ-crystallins are reduced by 50% in homozygous lenses relative to wild type. Homozygous lenses are insensitive to cold-induced cataracts.

Heterozygous: Heterozygous mice develop whole cataracts and have slightly small lenses. Lens fibers are slow to eliminate their nuclei and still have nuclear remnants at 3 weeks of age. Total levels of water-soluble γ- crystallins are reduced by 12% in heterozygous lenses relative to wild type.

Strain Development
The L23 mutant was identified by slit- lamp examination (which detects cataracts) among G1 mice born to ENU- mutagenized sires C57BL/6J; all subsequent crosses to maintain strain were on a C57BL/6J background only.

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.

Colony and Husbandry Information

Colony Surveillance Program and Current Health 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 mmrrc@ucdavis.edu.

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 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.

*Shipping & Handling not included*
Units Notes
030338-UCD-EMBRYO Cryo-preserved embryos $1,038.00 / Non-Profit Aliquot Approximate quantity2 : 20-40 embryos / aliquot
030338-UCD-SPERM Cryo-preserved spermatozoa $546.25 / Non-Profit Aliquot Approximate quantity3
030338-UCD-RESUS Litter recovered from cryo-archive $4,044.00 / Non-Profit Litter Recovered litter4; additional fees for any special requests.

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.
