Notes

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

J:95898

Linkage analysis was performed on 400 (C57BL/6J x DBA/2J)F2 animals and 26 BXD RI strains to identify QTLs associated with skeletal phenotypes. A panel of 672 microsatellite markers was used in the genome scan for the BXD RI group and 96 microsatellite markers at a resolution of 15-20 cM were used in the genome scan for the F2 group. Loci identified with significant linkage in the F2 group and confirmed in the BXD RI group are reported here.

A locus on mouse Chromosome 2 from 80 cM - 102 cM showed linkage to femur and tibia cortical thickness, ultimate load, and femur yield load. This locus is named Bntq3 (bone traits QTL 3). Maximal linkage occurs at 81 cM for femur length (LOD=6). Previously mapped QTLs near Bdt1 (84.2 cM), Bmd6 (86.3 cM), and Fembrs1 (65 cM). Potential candidate genes mapping near Bntq3 are Bmp2 (76.1 cM), Src (89 cM), Gdf5 (90 cM), and Mmp9 (96 cM).
