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.Read More +
This strain is homozygous for Cdh23ahl, the age related hearing loss 1 mutation, which on this background results in progressive hearing loss with onset after 10 months of age.
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).
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.

|Gene Symbol and Name||Ahr, aryl-hydrocarbon receptor|
|Strain of Origin||Not Applicable|
|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.|
|Allele Name||age related hearing loss 1|
|Allele Synonym(s)||Cdh23753A; mdfw|
|Gene Symbol and Name||Cdh23, cadherin 23 (otocadherin)|
|Strain of Origin||multiple strains|
|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.|
|Allele Type||Spontaneous (Null/Knockout)|
|Gene Symbol and Name||Gpr84, G protein-coupled receptor 84|
|Strain of Origin||multiple strains|
|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.|
