Notes

Mapping and Phenotype information for this QTL, its variants and associated markers

J:93737

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.

Linkage to anti-red blood cell IgG production at 10 months of age mapped to 31.2 cM - 31.7 cM on mouse Chromosome 9 (P=1.3 x 10-2). This locus is named Arigg8 (anti-RBC IgG antibodies 8). BALB/cByJ-derived alleles confer increase IgG antibodies at this locus.
