Open Access Abstract Collagen-induced arthritis in mice is one of the most commonly used autoimmune experimental models with many similarities to rheumatoid arthritis. Since collagen-induced arthritis is a complex polygenic disease there is a need for identification of several major disease-controlling genes. Because rheumatoid arthritis particularly affects aged women we have in the present study identified new genetic regions critical for collagen-induced arthritis by studying aged female mice of a cross between NFR N and B10.Q H-2q haplotype . The mice in the present study had different reproductive histories which did not significantly affect the onset incidence or severity of the disease. A total of 200 female mice were used in a total genome wide screening with 125 microsatellite markers. We found one new significant quantitative trait locus affecting the arthritis .
