(BALB/cCrl x DBA/2Crl)F2 animals were screened for 106 polymorphic markers on 19 autosomes at an average marker spacing of 15 cM (94% coverage of genome) to identify QTLs associated with rheumatoid arthritis (RA) phenotypes (autoantibody production and inflammation). Parental inbred strain BALB/cCrl is susceptible to RA when immunized with cartilage proteoglycan whereas DBA/2Crl is resistant to RA. (BALB/cCrl x DBA/2Crl)F1 animals exhibit arthritis resistance similar to parental strain DBA/2Crl. 12 Pgia (proteoglycan induced arthritis) QTLs were identified. Pgia1 affects autoantibody production and maps to mouse Chromosome 1 at 24 cM in linkage with D1Mit170 (LOD = 4.3). Pgia2 affects autoantibody production and maps to mouse Chromosome 2 at 80 cM in linkage with D2Mit166 (LOD = 11.1). Pgia3 affects autoantibody production and inflammation and maps to mouse Chromosome 7 at 40 cM in linkage with D7Mit62 (LOD = 5.3). Pgia3 maps near Lmb3, a QTL associated with Lupus in MRL and C57BL/6 F2 mice. Pgia4 affects autoantibody production and maps to mouse Chromosome 8 at 16 cM in linkage with D8Mit224 (LOD = 18.9). Pgia5 affects inflammation and maps to mouse Chromosome 9 at 36 cM in linkage to D9Mit104 (LOD = 10.1). Pgia6 affects autoantibody production and mapsto mouse Chromosome 10 at 16 cM in linkage to D10Mit282 (LOD = 7.1). Pgia7 affects autoantibody production and maps to mouse Chromosome 11 at 34 cM in linkage to D11Mit90 (LOD = 16). Pgia8 and Pgia9 both affect inflammation and map to mouse Chromosome 15at 20 cM (LOD = 8.4 at D15Mit7) and 41 cM (LOD = 6 at D15Mit41), respectively. Pgia8 maps near Eae2, a QTL associated with experimentally induced allergic encephalomyelitis. Pgia10 affects autoantibody production and inflammation and maps to mouse Chromosome 16 at 66 cM in linkage to D16Mit152 (LOD = 8.0). Pgia11 affects autoantibody production and maps to mouse Chromosome 18 at 50 cM in linkage to D18Mit80 (LOD = 11.9). Pgia12 affects inflammation and maps to mouse Chromosome 19 at 54 cM in linkage to D19Mit71 (LOD = 8).
