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.
  
  A novel locus associated with CIA, Cia18, maps to Chromosome 18 to an interval spanning 50cM-55cM, flanked by markers D18Mit80 and D18Mit128. Cia18 is linked to autoantibody production (LOD=3.4).
