Notes

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

J:73060

Composite interval mapping (CIM) was used for localization of QTL involved in modulating response to infection with Borrelia burgdorferi. Parental strains C3H/HeN and C3H/HeJ are susceptible to B.burgdorferi-induced arthritis whereas parental strains C57BL/6N and BALB/cAnN are resistant. Four different backcrosses and the reanalysis of a previous intercross were performed.

A novel QTL, Bbaa18, was identified in the (C57BL/6N X C3H/HeN)F1 X C57BL/6N backcross on Chr 10. Bbaa18 was linked to specific IgMlevels after infection with B.burgdorferi. It mapped to 31.5 cM with marker D10Mit130, LRT=16.7 accounting for 12.2% variance.

[Table 2.]

C3H/HeN-derived alleles are associated with increased arthritis susceptibility and severity at all QTL mapped in this experiment.
