Notes
Pgia26 interacts with Pgia25 on chromosome X. Animals homozygosous for BALB/cCrl alleles at Pgia26 and homozygous for DBA/2Crl alleles at Pgia25 exhibit increased arthritis onset scores.

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

J:84150

Linkage analysis was performed on 559 proteoglycan-immunized (BALB/cCrl x DBA/2Crl)F2 animals to detect QTLs associated with arthritis susceptibility, severity, and onset. BALB/cCrl females are 100% susceptible to proteoglycan-induced arthritis (PGIA) whereas DBA/2Crl males are resistant. F1 hybrid males and females are also resistant to PGIA.

Several previously identified PGIA loci were confirmed in this study. These include Pgia1, Pgia4, Pgia6, Pgia7 Pgia8, Pgia9, and Pgia12.

Authors identify novel PGIA loci:

Pgia26 mapped to 52.5 cM on mouse Chromosome 3 with LOD=4.9 at D3Mit158 for arthritis onset in female animals. The Pgia26 QTL interval spans 34 cM - 80 cM on chromosome 3. BALB/cCrl-derived alleles confer high arthritis onset with codominant inheritance at Pgia26.

Pgia27 mapped to 42.5 cM on mouse Chromosome 4 with LOD=3.1 at D4Mit45 for arthritis severity in male animals. The Pgia27 QTL interval spans 35 cM - 45 cM on chromosome 4.

Pgia28 mapped to 14 cM on mouse Chromosome 11 with LOD=2.8at D11Mit229 for hetero antibody production in male animals. The Pgia28 QTL range spans 0 cM - 28 cM on chromosome 11.

Pgia29 mapped to 45 cM on mouse Chromosome 14 with LOD=2.8 for arthritis severity in male animals and LOD=3.5 for T cell proliferation in female animals at D14Mit92. The Pgia29 QTL range spans 40 cM - 54 cM on chromosome 14.
