Notes

• Experiment
  135 SSLP markers were screened in a set of 939 (BALB/cCrl x DBA/1J)F2 intercross animals to identify QTLs associated with collagen-induced arthritis (CIA) and proteoglycan-induced arthritis (PGIA). Parental strain BALB/cCrl is CIA-resistant and PGIA-susceptible while parental strain DBA/1J is CIA-susceptible and PGIA-resistant.
  
  A major locus was identified on mouse Chromosome 17 in linkage to both CIA (LOD=21) and PGIA (LOD=6). This locus, Pgia17, has been previously identified and maps to proximal Chromosome 17.
  
  Pgia21, a novel locus associated with PGIA, maps to mouse Chromosome 7 at approximately 43 cM with peak marker D7Mit62. Pgia21 is linked to IL-2 production (LOD=8.1).
