Notes

• Experiment
  Advanced intercross lines derived from LG/J and SM/J parental inbred strains at the F9 (n=150) and F10 (n=1305) generations were used to confirm and refine previously identified QTL (from F2-F3 generations) for long bone traits and identify novel geneticloci and interacting QTL. Animals were phenotyped between 12 and 40 weeks of age and genotyped at 1470 polymorphic SNP loci. The average distance between markers is 1.66 Mb. Long bone measurements were taken for the right-side tibia, femur, humerus and ulna. Eighty-one single-trait QTL were detected in this study, which includes 27 previously identified long bone loci. Thirteen novel pleiotropic loci were detected.
  
  Previously identified QTL Lbn5 on mouse Chromosome 6 was refined into two separate QTL inthis study. Lbn5a (long bones 5a) mapped to 4.4 cM near rs3710004 and is associated with femur (LPR=5.44), ulna (LPR=12.68), tibia (LPR=15.81) and humerus (LPR=4.39) lengths. Lbn5b (long bones 5b) mapped to approximately 20.5 cM near rs3684860 and is associated with tibia (LPR=7.49), humerus (LPR=5.12), ulna (LPR=7.78) and femur (LPR=9) lengths. A novel locus named Lbn5c (long bones 5c) mapped to the distal part of chromosome 6 at 71 cM near rs4140069. Lbn5c displays linkage to ulna (LPR=4.14), femur (LPR=3.45) and tibia (LPR=4.07) lengths.
