Notes

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

J:82018

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.

Two novel loci associated with CIA mapped to mouse Chromosome 1.

Cia20 (mCia14) mapped to peak marker D1Mit65 at approximately 8 cM. Cia20 is linked to IFN-gamma production (LOD=2.9).

Cia15 (mCia15) mapped to an interval spanning 33cM - 54cM, flanked by markers D1Mit76 and D1Mit48, and is linked to soluble CD44 production (LOD=2.8).
