Notes

• Experiment
  Linkage analysis was performed on 542 female (NZB/BlNJ x RF/J)F2 intercross animals to identify QTLs associated with serum lipid levels. F2 female animals were fed a CHOW diet and sacrificed at 10 weeks of age for phenotype analysis. A panel of 94 polymorphic markers was used for linkage analysis. Parental strain NZB/BlNJ displays 48% increased plasma cholesterol and 57% increased plasma HDL compared to RF/J, and parental strain RF/J has 58% increased triglycerides and 10% higher body weight compared to NZB/BlNJ.
  
  Data from a previously studied population of 621 (MRL/MpJ x SJL/J)F2 females was also used for a combined analysis. A set of 231 microsatellite markers was used to genotype the combined data set.
  
  In the combined cross analysis [Table. 2.]:
  
  A QTL on mouse Chromosome 14, Chldq8 (cholesterol and HLD QTL 8) linked to plasma cholesterol (LOD=4.52) and HDL (LOD=4.05) mapped to 34 cM on mouse Chromosome 14 in the combined data set. The 95% confidence interval spans 28 cM - 42 cM.
