Notes

• Experiment
  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, Bbaa19, was identified in the (C57BL/6N X C3H/HeN)F1 X C57BL/6N backcross on Chr 16. Bbaa19 was linked to specific IgG levels after infection with B.burgdorferi. It mapped to 9.7.0 cM with marker D16Mit88, LRT=16.8 accounting for 11.2% variance.

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