Overview

Also Known As:Large

LG/J mice develop antinuclear antibodies and rheumatoid factor as well as renal disease characterized by glomerulonephritis, interstitial nephritis, and perivasculitis. LG/J mice are often compared to SM/J (Stock No. 000687) for quantitative trait locus analysis in the areas of atherosclerosis, obesity, and mandible size . These mice are susceptible to diet-induced obesity and diet-induced atherosclerosis. This strain is among the least responsive to phytohemagglutinin.

Important Note

This strain is homozygous for Cdh23^ahl, the age related hearing loss 1 mutation, which on this background results in progressive hearing loss with onset after 10 months of age.

Detailed Description

LG/J mice develop antinuclear antibodies and rheumatoid factor as well as renal disease characterized by glomerulonephritis, interstitial nephritis, and perivasculitis (Peng et al., 1996). LG/J was the predominant strain used to develop the MRL/LpJ (Stock No. 000486) inbred strain, a model for autoimmunity. LG/J mice are often compared to SM/J (Stock No. 000687) for quantitative trait locus analysis in the areas of atherosclerosis, obesity, and mandible size . These mice are susceptible to diet-induced obesity and diet-induced atherosclerosis. This strain is among the least responsive to phytohemagglutinin (Heiniger et al., 1975).

Development

Developed by Goodale with selection for large body size begining in 1931. Inbred by M.N. Runner. Two substrains, J and Ckc, were separated at F27.

Ahr^d

Allele Symbol: Ahr^d

Allele Name	d variant
Allele Type	Not Applicable
Allele Synonym(s)	ah; Ah^d; Ah^k; Ahhⁿ; AhRd; in
Gene Symbol and Name	Ahr, aryl-hydrocarbon receptor
Gene Synonym(s)
Strain of Origin	Not Applicable
Chromosome	12
General Note	Strain of origin - this allele was found in DBA/2J, AKR/J, 129, SWR, RF, NZB strains
Molecular Note	This allele encodes a 104 kDa receptor that is stabilized by molybdate and has an affinity for ligand 10-100 fold lower than that of the receptor produced by the C57BL/6J allele. PCR sequencing of cDNA revealed ten nucleotide differences between the coding sequences of the DBA/2J and C57BL/6J receptors. Five of the ten differences would cause amino acid changes. One of these, an apparent T to C transition replaces the opal termination codon in the C57BL/6J allele with an arginine codon in the DBA/2J allele. This change would extend translation of the DBA/2J mRNA by 43 amino acids, accounting for the larger size of the peptide produced by this allele (104 kDa vs 95 kDa for the C57BL/6J allele). A second T to C transition changes a leucine codon in the C57BL/6J allele to a proline codon in the DBA/2J allele, and would likely change secondary structure of the peptide and thus ligand affinity.

Cdh23^ahl

Allele Symbol: Cdh23^ahl

Allele Name	age related hearing loss 1
Allele Type	Spontaneous
Allele Synonym(s)	Cdh23^753A; mdfw
Gene Symbol and Name	Cdh23, cadherin 23 (otocadherin)
Gene Synonym(s)
Strain of Origin	multiple strains
Chromosome	10
Molecular Note	Genetic complementation tests have shown allelism between the mdfw (modifier of deaf waddler) locus and the ahl locus. Further analysis has shown this is caused by a G to A transition at coding nucleotide position 753 of Cdh23 (SNP rs257098870). This hypomorphic allele changes splice donor site G-GT to A-GT, causing frame skipping of exon 7. This is predicted to delete part of the 2nd and 3rd ectodomains and cause reduced message stability. Twenty-seven strains classified with ahl and carrying the 753A allele include: CD-1, RBF/DnJ, PL/J, AKR/J, RF/J, BALB/cBy, A/WySnJ, P/J, SENCARA/PtJ, DBA/1J, ALS/LtJ, C58/J, C57BLKS/J, 129P1/ReJ, C57BR/cd, SKH2/J, BUB/Bn, MA/MyJ, LP/J, 129X1/SvJ, NOR/LtJ, A/J, C57BL/6, NOD/LtJ, DBA/2J, ALR/LtJ, C57L/J. Strains classified with ahl that DO NOT carry this mutation include: 129S1/SvImJ, C3H/HeSnJ, I/LnJ, YBR/Ei, MRL/MpJ.

Gpr84^del

Allele Symbol: Gpr84^del

Allele Name	deletion
Allele Type	Spontaneous (Null/Knockout)
Allele Synonym(s)
Gene Symbol and Name	Gpr84, G protein-coupled receptor 84
Gene Synonym(s)
Strain of Origin	multiple strains
Chromosome	15
Molecular Note	This spontaneously arising frameshift deletion is located in exon 2 at position 103308576 bp (NCBI Build 37) and results in a premature stop codon. The mutation is predicted to result in a truncated protein lacking the transmembrane domains 4-7. The inbred strains BDP/J, DBA/1J, DBA/2J, I/LnJ, FVB/NJ, LG/J, MRL/MpJ, NODShi/LtJ, NOR/LtJ, P/J, PL/J, SKHIN/Sprd, SJL/J, SM/J are homozygous for the deletion. The allele is segregating in the outbred stocks ICR and CD-1.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
