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.

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).

(** D18Mit128 has been withdrawn, now D14Mit1004.)
