This coisogenic strain has a functional allele of Gpnmb. Homozygous mice do not develop the elevated intraocular pressure or glaucoma found in DBA/2J mice (Stock No. 000671), although they exhibit a mild iris stromal atrophy (ISA). This strain provides a genetically matched control for DBA/2J.

This coisogenic strain has a functional allele of Gpnmb. Homozygous mice do not develop elevated intraocular pressure or glaucoma, although they exhibit a mild iris stromal atrophy (ISA). This strain provides a genetically matched control for DBA/2J (Stock No. 000671). The inbred strain DBA/2J is homozygous for the glaucoma-related GpnmbR150X and Tyrp1isa mutations.
The wildtype allele of Gpnmb is present in the mutant strain DBA/2J-Dtnbp1sdy/J. The sandy mutation occurred in 1983 prior to the appearance of the GpnmbR150X mutation in the The Jackson Laboratory DBA/2J production colony. To generate this strain, mice from DBA/2J-Dtnbp1sdy/J were crossed to "modern" DBA/2J mice, and progeny were selected for the Gpnmb wildtype allele. The wildtype allele was backcrossed to DBA/2J for a minimum of six generations. Dr. Simon John of The Jackson Laboratory provided the colony to the Repository in 2007.

General Note | This is an allele characteristic of various inbred mouse strains including the following: A/HeJ, A/J, AKR/J, DBA/2J, NZB/B1NJ, SWR/J, B10.D2/oSnJ Hc was identified as a candidate gene for Abhr2 in a microarray analysis of lung mRNA from A/J, C3H/HeJ, and (A/J x C3H/HeJ)F1 x A/J backcross animals. Hc genotype shows statistically significant correlation to allergen-induced bronchial hyperresponsive phenotype. The A/J allele contains a 2 bp deletion resulting in deficient Hc mRNA and protein production and is associated with susceptibility to allergen-induced bronchial hyperresponsiveness. (J:108211) |
Molecular Note | A 2 base "TA" deletion at positions 62 and 63 of an 83 base pair exon near the 5' end of the gene is found in the following mouse strains: A/HeJ, A/J, AKR/J, DBA/2J, I/LnJ, KK/HlJ, MOLF/EiJ, NZB/B1NJ, RF/J, ST/bJ SWR/J, B10.D2/oSnJ. The consequence of this deletion is the creation of a stop codon starting four bases after the deletion. A truncated product of 216 amino acids is predicted as a result although contradictory reports exist that a larger pro-C5 protein may be synthesized. Nevertheless, macrophages from mouse strains carrying this allele do not secrete complement 5. |

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. |
When maintaining a live colony these mice can be bred as homozygotes.

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.
