Mating System Sibling x Sibling         (Female x Male)   01-MAR-06 Species laboratory mouse RI progenitor BALB/cBy C57BL/6By H2 Haplotype b Generation F140 (19-NOV-09)

Appearance
black
Related Genotype: a/a Tyrp1⁺/Tyrp1⁺ Tyr⁺/Tyr⁺

Description
The CXB7/ByJ recombinant inbred strain is widely used because of a deficiency in mu opioid receptors. Like BALB/cByJ, this recombinant inbred carries the mutation hippocampal lamination defect or Hld, an allele responsible for abnormal neuronal migration to the pyramidal cell layer (Nowakowski RS, et al, Jnl Neurogen, 1984).

Development
BALB/cBy and C57BL/6By inbred strains are the progenitors to the set of CXB recombinant inbred strains developed by Dr. Don Bailey of The Jackson Laboratory.

Genes & Alleles

Gene & Allele Information

Allele Symbol		Ahrb-2
Allele Name		b-2 variant
Allele Type		Not Applicable
Common Name(s)		Ahb-2; Ahh;
Strain of Origin		BALB/cBy
Gene Symbol and Name		Ahr, aryl-hydrocarbon receptor
Chromosome		12
Gene Common Name(s)		Ah; Ahh; Ahre; In; aromatic hydrocarbon responsiveness; aryl hydrocarbon hydroxylase; bHLHe76; dioxin receptor; inflammatory reactivity;
General Note		C57BL/6 carries the responsive Ahrb allele; DBA/2 carries nonresponsive Ahrd. Heterozygotes (Ahrb/Ahrd) are responsive (J:5282). Later work identified a second (J:8895) and later a third (J:22144) allele conferring response. Thus the allele in C57, C58, and MA/My strains is now Ahrb-1; Ahrb-2 is carried by BALB/cBy, A, and C3H; and Ahrb-3 by Mus spretus, M. caroli, and MOLF/Ei. The nonresponsive strains AKR, DBA/2, and 129 carry Ahrd (J:22144). Nucleotide and amino acid sequence differences between Ahrb-1 and Ahrd have been determined (J:17460). Strain of origin - this allele was found in BALB/cByJ, A/J, C3H/HeJ, CBA strains
Molecular Note		This allele encodes a high affinity, heat labile, 104 kDa receptor containing 848 amino acids. Sequencing studies of cDNA from C57BL/6J congenic mice homozygous for this allele identified nucleotide substitutions in the ORF that would cause 5 amino acid differences between the C57BL/6J and BALB/cBy peptides, and 2 amino acid differences between the BALB/cBy and DBA/2J peptides. A T to C transition in exon 11 replaces the opal termination codon in the C57BL/6J allele with an arginine codon in the BALB/cByallele. This change would extend translation of the BALB/cBy 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). [MGI Ref ID J:15153] [MGI Ref ID J:22144]
Allele Symbol		Hld
Allele Name		hippocampal lamination defect
Allele Type		Spontaneous
Strain of Origin		BALB/cJ
Gene Symbol and Name		Hld, hippocampal lamination defect
Chromosome		UN
General Note		Abnormal laminar organization of the pyramidal layer of the cerebellum, particularly in the proximal segment of the layer, occurs in the BALB/cJ strain (J:5787). A single gene, Hld for hippocampal lamination defect, was shown to cause this abnormality in a cross of BALB/c with C57BL/6 and in the CXB recombinant inbred strains (J:13989). In normal strains, the latest formed or youngest neurons migrate past the earlier formed or older neurons to a position in the pyramidal layer that is superficial to that of the older cells. In BALB/cJ, the positions are reversed, with the older cells lying superior to the younger ones (J:5787). Since mossy fibers form synapses primarily with the older cells, this aberrant pattern of cell migration in BALB/c leads to adifferent pattern of mossy-fiber synapses, easily visualized with Timm's stain (J:5486). The dendritic excrescences induced by contact with mossy fibers on late-generated pyramidal cells in +/+ mice occur at sites on both the apical and basal dendrites; in Hld/Hld mice, they occur in two sites on the apical dendrites only (J:12029).

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.
