Notes

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

J:89536

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 are fully 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 whereas parental strains BALB/c and DBA/2 are fully resistant. All F1s exhibited susceptibility to CIA.

Cia33 (mCia5 used Figure 3) mapped to proximal mouse Chromosome 3 in association with CIA severity (LOD=5) in the MHC-unmatched (BALB/c x DBA/1J)F2 population.
