Detailed Description

I/LnJ mice were originally derived by Dr. LC Strong in 1926 from an unpedigreed stock of mice. A high proportion of mice from this strain lack a corpus callosum. This absence is associated with slow growth of the medial septum subadjacent to the cavum septi. I/LnJ mice are resistant to MMTV induced mammary tumor development and generate neutralizing antibodies to MMTV and MuLv virions that effectively block viral transmission. This phenotype was traced to the I/LnJ loss-of-function allele, vic1, in H2-Ob (Denzin et al., 2017). Due to a frameshift mutation in alpha 1 phosphorylase kinase these mice have increased glycogen content in resting skeletal muscle. The reproductive performance of I/LnJ mice is very poor. Further analysis indicates that oocytes from I/LnJ mice display retarded kinetics of meiotic maturation and a high frequency of metaphase I arrest. Some oocytes fail to resume meiosis. Oocytes have many very small centrosomes with an absence of microtubules. I/LnJ mice, in addition to carrying several other coat color alleles, are homozygous for the piebald mutation (Ednrb^s). Thus, these mice show irregular white spotting, the amount of which is greatly influenced by minor modifying genes. They also have dark eyes. The white areas of the coat are completely lacking in neural crest-derived melanocytes, and there is a reduction in the number of melanocytes in the choroid layer of the eye. Although kinked tail is not a phenotype noted at birth, approximately 10% of pups at wean age and 20% of breeders have a single kink in the tail. This phenotype was recorded in 2006, and whether this strain characteristic was part of the original phenotype of this inbred strain or arose subsequent to inbreeding is not known.

Myo5a^d

Allele Symbol: Myo5a^d

Allele Name	dilute
Allele Type	Spontaneous
Allele Synonym(s)	blue dilution; d; d^v; Maltese dilution
Gene Symbol and Name	Myo5a, myosin VA
Gene Synonym(s)
Strain of Origin	old mutant of the mouse fancy
Chromosome	9
Molecular Note	This mutation is the result of the integration of ecotropic murine leukemia virus Emv-3 into a noncoding region of the Myo5a^d gene. Reversions of Myo5a^d to wild-type are caused by excision of the virus leaving exactly one long terminal repeat in place.

Ednrb^s

Allele Symbol: Ednrb^s

Allele Name	piebald
Allele Type	Spontaneous
Allele Synonym(s)	pied spotting; s
Gene Symbol and Name	Ednrb, endothelin receptor type B
Gene Synonym(s)
Strain of Origin	old mutant of the mouse fancy
Chromosome	14
General Note	Also called piebald spotting. This is a very old mutation of the mouse fancy, and was described in the scientific literature as early as 1920 (J23183). Some piebalds in existing stocks may be of independent origin.
Molecular Note	This mutation is allelic to a targeted mutation for this gene. Homozygous mice produce approximately 25% of the normal levels of transcript from this allele. RT-PCR analysis demonstrated that no alterations in the coding sequence would result in any alteration of the amino acid sequence. A 5.5 kb retrotransposon-like element is found in intron 1. About 75% of the mRNA produced is an aberrant 6.5 kb form lacking exons 2-6 but containing exon 1. The remaining 25% of the mRNA formed is of normal, 4.4 kb, size.

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.

Hc⁰

Allele Symbol: Hc⁰

Allele Name	deficient
Allele Type	Spontaneous
Allele Synonym(s)	C5-; C5-d; C5-def; C5-deficient; Hc^Hfib2; hc^o
Gene Symbol and Name	Hc, hemolytic complement
Gene Synonym(s)
Strain of Origin	multiple strains
Chromosome	2
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.

Mx1^s2

Allele Symbol: Mx1^s2

Allele Name	myxovirus susceptibility 2
Allele Type	Spontaneous (Null/Knockout)
Allele Synonym(s)
Gene Symbol and Name	Mx1, MX dynamin-like GTPase 1
Gene Synonym(s)
Strain of Origin	multiple strains
Chromosome	16
General Note	The Mx genes determine resistance to the lethal effects of various myxoviruses including neurotropic avian influenza A virus injected intracerebrally, pneumotropic strains injected intranasally, and a hepatotropic strain injected intraperitoneally (J:5645, J:13136). Resistance is not dependent on presence of the thymus and is not abolished by immunosuppression or by inhibitors of macrophage function (J:5735, J:5478, J:5645). Resistance is specific for the orthomyxoviruses (J:6265). It is dependent on the presence of interferon-alpha and -beta but not -gamma (J:7365). The resistance allele at the Mx1 locus, under induction by alpha/beta interferon, produces the 75 kDa protein MX-1, which confers resistance to the influenza virus, in the nuclei of cells carrying the allele. Susceptibility alleles do not produce the protein (J:8273). The protein is located in the nucleus (J:7703) and produces its antiviral effect by preventing synthesis of viral mRNA in the nucleus (J:7992). Nuclear localization is necessary for anti-influenza virus activity (J:1417), but mutations induced in Mx1 showed that nuclear position was not sufficient for the effect; mutations in several domains can cause its loss (J:11840). The MX-1 protein is a GTPase containing a GTP binding domain (J:1417) and this binding core is also necessary (J:21243). Resistance is expressed by macrophages and other cells in vitro (J:6649, J:5940) but could not be transferred to susceptible animals by transfer of macrophages from resistant mice (J:6149). Resistance to infection with two tick-borne viruses, Thogoto virus (J:8273) and Dhori virus (J:27760), is also conferred by Mx1^r. The Mx1^r allele occurs only in strains A2G, SL/NiA, and T9, the latter being a strain derived from an influenza-resistant wild stock, and CAST/Ei, derived from Mus musculus castaneus. Most inbred strains, including C57BL/6J, C3H/HeJ, and BALB/cJ, carry an influenza susceptible Mx1^s1 allele which produces mRNA lacking exons 9, 10, and 11 of the Mx1^r allele. This large deletion apparently renders the protein incapable of providing resistance to influenza. The CBA/J, CE/J, I/LnJ, and PERA/Ei strains, also susceptible to the virus, have another form of the Mx1^s2 allele in which there is a nonsense mutation (J:9452). Interferon is induced by viral infection and in turn induces the Mx protein (J:7703). Although some interferon-induced genes respond directly to virus invasion as well as indirectly through induction by virus-induced interferon, this primary response is very weak for the MX-1 protein in response to either influenza or Newcastle disease viruses (J:1892).
Molecular Note	CBA/J, CE/J, I/LnJ and PERA/Ei strains have a nonsense mutation that results in a null allele and susceptibility to myxoviruses.
