The AXB and BXA set of RI strains are useful in the genetic analysis of complex diseases. The individual strains within the RI set also differ in their susceptibility to infectious diseases and in their responses to alcohol, stress, and endotoxin. AXB and BXA strains are derived from the C57BL/6J (Stock No. 000664) and A/J (Stock No. 000646) progenitor strains.Read More +
This strain is homozygous/hemizygous for Cacna1fnob2, no b wave 2, which results in impaired light- and dark-adapted electroretinogram responses.
The AXB and BXA set of RI strains are useful in the genetic analysis of several complex diseases including cardiovascular disease, diabetes, cancer, cleft palate, and hydrocephalus. The individual strains within the RI set also differ in their susceptibility to infectious diseases and in their responses to alcohol, stress, and endotoxin.
The strain distribution pattern (SDP) for the AXB RI strains is available through the Mouse Genome Informatics
Contributed Data Sets and Gene Network.
Additional tools and information are presented through the Mouse Phenome Database
Specialized Strain Panel Query Form, and
Gene Network .
The AXB and BXA recombinant inbred (RI) set of strains were originally generated and maintained at the University of California, San Diego, and have been imported into The Jackson Laboratory. There were originally 51 AXB and BXA strains derived from the C57BL/6J (Stock No. 000664) and A/J (Stock No. 000646) progenitor strains. Many of the original strains are either extinct or were discarded due to genetic contamination. Please refer to Sampson et al., 1998 for more information.
|Gene Symbol and Name||Nrg3, neuregulin 3|
|Strain of Origin||A/J|
|Molecular Note||This allele maps to an interval between the microsatellite markers D14Mit14 and D14Mit80 located at 10.0 cM and 13.5 cM. The mutation identified is a microsatellite repeat within intron 7 of the gene. This simple sequence repeat (SSR) was found to completely cosegregate with the ska phenotype.|
|Allele Name||no b wave 2|
|Allele Synonym(s)||Cav1.4nob2; nob2|
|Gene Symbol and Name||Cacna1f, calcium channel, voltage-dependent, alpha 1F subunit|
|Strain of Origin||AXB6/PgnJ|
|Molecular Note||Sequence analysis identifies this allele as an insertion of a transposable element in exon 2. The out-of-frame insertion produces a stop codon after synthesis of 32 amino acids. Immunofluorescent staining using an antibody directed to the C terminal of the subunit protein indicates that it is not expressed in the inner or outer plexiform layers of the retina.|
