Notes

• Experiment
  Linkage analysis was performed on 222 female animals from a (NZB/BlNJ x BALB/cByJ)F2 intercross to identify QTLs associated with susceptibility to autoimmune hemolytic anemia (AHA) and systemic lupus erythematosus (SLE). 96 polymorphic markers at an average spacing of 17 cM were used in the genome scan. Parental strain NZB/BlNJ is susceptible to autoimmune hemolytic anemia and exhibits elevated serum levels of anti-red blood cell antibodies compared to BALB/cByJ. NZB/BlNJ is also susceptible to systemic lupus erythematosus and exhibits elevated serum levels of antinuclear antibodies compared to parental strain BALB/cByJ.
  
  On mouse Chromosome 3, linkage to anti-red blood cell IgG antibody production at 8 months of age mapped to 16.5 cM - 17.8 cM (P=7.8 x 10-3). This locus is named Arigg1 (anti-RBC IgG antibodies 1). NZB/BlNJ-derived alleles confer increased IgG antibody production at Arigg1.
