Notes

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

J:66636

Linkage analysis using 139 markers at a density of 10 cM was performed on an MRL/MpJ-Tnfrsf6^lpr/Tnfrsf6^lpr x (C3H/HeJ-Tnfrsf6^lpr/Tnfrsf6^lpr x MRL/MpJ-Tnfrsf6^lpr/Tnfrsf6^lpr)F1 backcross population to map loci associated with 4 types of lesions involved in collagen disease: vasculitis, glomerulonephritis, arthritis, and sialoadenitis. Parental strain MRL/MpJ-Tnfrsf6^lpr/Tnfrsf6^lpr is susceptible to collagen disease whereas parental strain C3H/HeJ-Tnfrsf6^lpr/Tnfrsf6^lpr is resistant. A locus significantly linked to sialoadenitis susceptibility, Sials, in females mapped to mouse Chromosome 4 at approximately 48.5 cM (P<0.0001 at D4Mit255). The MRL/MpJ-derived allele confers recessively inherited susceptibility to sialoadenitis in female animals at this locus. Suggestive loci were also detected for susceptibility to vasculitis (P<0.0009 at D4Mit125), glomerulonephritis (P<0.0007 at D6Mit8), arthritis in males (P<0.0009 at D15Mit183), and sialoadenitis (P<0.0009 at D10Mit20 and D10Mit259).
