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 +
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.
In 2004 a phenotype of small body size was found to be segregating in this colony after recovery from cryopreservation. It appears that this phenotype is segregating recessively in this strain and is present in the cryopreserved bank stock. The expressed phenotype is small size relative to littermates and mice with this diminished body size often catch up to their littermantes in body size after wean age.
The strain distribution pattern (SDP) for the BXA 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.|
