Notes

• Experiment
  Disease phenotypes associated with Leishmania major infection were mapped in animals from (CcS-16 x BALB/cHeA)F2 and (CcS-20 x BALB/cHeA)F2 intercross populations. CcS-16 and CcS-20 are recombinant congenic (RC) strains derived from STS/A and BALB/cHeA. Animals were infected with Leishmania major after 9 weeks of age and sacrificed 8 weeks post-infection.
  
  F2 hybrids between BALB/c and CcS20/Dem and F2 hybrids between BALB/c and CcS16 were tested from clinical and immunological consequences post infection. They were genotyped with mircosatellite markers covering the STS-derived segments. Linkage analysis of differing pathological and immunological parameters indicated novel loci and novel functions for previously mapped loci.
  
  In the (BALB/c x CcS20)F2 intercross a previoulsy mapped QTL, Lmr9, mapping with D4Mit149 was identified.
  A new function was linked with this QTL:
  Lmr9b, mapped with marker D4Mit149, corrected p=0.0182 and was associted with IL-6 levels in serum. STS/A alleles at this locus were associated with higher IL-6 levels.
