Notes

• Experiment
  Linkage analysis at an average resolution of 10 cM was performed on 3 separate mouse crosses to map QTLs associated with proteoglycan-induced arthritis (PGIA) and collagen-induced arthritis (CIA).
  
  559 (BALB/c x DBA/2)F2 MHC-matched animals and 402 (BALB/c x DBA/1J)F2 MHC-unmatched animals were analyzed for linkage to PGIA.
  
  537 (BALB/c x DBA/1J)F2 animals were analyzed for linkage to CIA.
  
  With respect to PGIA, parental strain BALB/c is highly susceptible where as parental strains DBA/2 and DBA/1J arefully resistant. As expected, (BALB/c x DBA/2)F1 hybrids are resistant to PGIA, but interestingly (BALB/c x DBA/1J)F1 hybrids are susceptible to PGIA. This is unusual because the BALB/c allele typically exhibits recessive susceptibility to disease, but this is not the case with the cross to DBA/1J.
  
  With respect to CIA, parental strain DBA/1J is highly susceptible where as parental strains BALB/c and DBA/2 are fully resistant. All F1s exhibited susceptibility to CIA.
  
  Pgia30 mapped to central mouse Chromosome 1 in association with PGIA severity (LOD=4) in the MHC-unmatched (BALB/c x DBA/1J)F2 population. This locus overlaps with QTL Cia15.
