GenerationF235 (03-JAN-08)

Appearance
leaden (grey)
Related Genotype: a/a Tyrp1b/Tyrp1b Mlphln/Mlphln

Important Note
This strain is homozygous for Cdh23ahl, the age related hearing loss 1 mutation, which on this background results in progressive hearing loss with onset prior to 3 months of age.

Strain Description
C57L/J mice are used widely in research as a general purpose strain. Mice have a high incidence of Hodgkin's-like reticulum cell neoplasm at 18 months of age and pituitary tumors in old multiparous females. C57L/J mice are highly susceptible to experimental allergic encephalomyelitis (EAE). In addition, C57L/J mice are highly susceptible to developing atherosclerotic aortic lesions (4500 to 8000 um2 atherosclerotic aortic lesions/aortic cross-section) following 14 weeks on an atherogenic diet (1.25% cholesterol, 0.5% cholic acid and 15% fat) (Paigen et al. 1990). On a lithogenic diet, C57L/J mice develop gallstones as a result of abnormal regulation of cholesterol synthesis (Xua et al., 2004). C57L/J mice carry no detectable endogenous ecotropic MuLV DNA sequences.

Strain Development
C57L/J mice were inbred following a mutation in a now extinct substrain of C57BR at F22. Inbreeding was carried out by J Murray at The Jackson Laboratory beginning in 1933. They were transferred to the production facility in 1947 at F45. The current generation of inbreeding is F203+.

Gene & Allele Details

Allele Symbol Cdh23ahl
Allele Name age related hearing loss 1
Common Name(s) Cdh23753A; mdfw;
Strain of OriginC57BL/6J
Gene Symbol and Name Cdh23, cadherin 23 (otocadherin)

Molecular Note Genetic complementation tests have shown allelism between the mdfw (modifier of deaf waddler) locus and the ahl locus. Further analysis has identified an association between ahl and a G to A transition at nucleotide position 753 of Cdh23. This hypomorphic allele causes in frame skipping of exon 7 and reduced message stability. Twenty-seven strains classified with ahl and carrying the 753A allele include: CD1, RBF/DnJ, PL/J, AKR/J, RF/J, BALB/cBy, A/WySnJ, P/J, SENCARA/PtJ, DBA/1J, ALS/LtJ, C58/J, C57BLKS/J, 129/ReJ, C57BR/cd, SKH2/J, BUB/Bn, MA/MyJ, LP/J, 129/ScJ, NOR/LtJ, A/J, C57BL/6, NOD/LyJ, DBA/2J, ALR/LtJ, C57L/J. Strains classified with ahl that DO NOT carry this mutation include: C3H/HeSnJ, I/LnJ,YBR/Ei, MRL/MpJ. [J:86905]

Chromosome 1
Gene Common Name(s) 2210418F23Rik; 5031433I09Rik; AW228792; D1Wsu84e; DNA segment, Chr 1, Wayne State University 84, expressed; MGC2771; MGC59733; SLAC2-A; Slac-2a; expressed sequence AW228792; l(1)-3Rk; l1Rk3; leaden; lethal, Chr 1, Roderick 3; ln;
General Note In its effect on coat color the leaden mouse is indistinguishable from the dilute mouse. Like dilute, this allele causes clumping of melanin granules into larger masses, but no change in color of the pigment. The clumping is due to the shape of the melanocytes, which have fewer and thinner dendritic processes than wild-type melanocytes (J:12970). These melanocytes are more easily dislodged from fixed sites in the hair bulb and incorporated into the developing hair, resulting in large clumps of pigmentin the hair shaft (J:5095). By use of chimeras and dermal-epidermal recombination grafts, the site of action was shown to be in the melanocytes (J:8167).
Molecular Note This allele has a C to T transition at mRNA nucleotide position 266. This introduces a stop codon in the sequence of the normally spliced transcript and it also creates a new splice donor site in exon 2. Use of this alternative splice site yields a transcript with an in-frame 21 base pair deletion that deletes 7 amino acids from the translated protein. Northern blots failed to detect this size difference and did not find any change from normal in transcript expression level. [J:71302]
 
Allele Symbol Obq3C57L/J
Allele Name C57L/J
Strain of OriginC57L/J
Gene Symbol and Name Obq3, obesity QTL 3
Chromosome 2
General Note Obq3 exhibits additive inheritance.
 
Allele Symbol Obq4C57L/J
Allele Name C57L/J
Strain of OriginC57L/J
Gene Symbol and Name Obq4, obesity QTL 4
Chromosome 17
General Note Obq4 may also be consistent with an additive mode of inheritance.
Molecular Note This allele confers increased adiposity in male animals compared to AKR/J. [J:39947]

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
