Supplemental Figure 1: Haplotype analysis for Prsq1-3 and Prsq4-5 intervals.

SNP data from the Mouse HapMap Imputed Genotype Resource (http://mouse.cs.ucla.edu/mouseHapMap/) were integrated with information on the set of mouse genes from the Ensembl Biomart resource ( http://www.ensembl.org/biomart). For each gene within the Prsq1-3 (Chr 2) or Prsq4-5 (Chr 4) interval, the haplotype was determined using all of the SNPs within the gene and the two flanking SNPs. Haplotypes were assigned in the strain order listed in each map, with black vertical bars indicating a haplotype matching FVB, red indicating B6, yellow indicating BALB, and green indicating D2. The horizontal lines above the map for each strain indicate the approximate 1 LOD support intervals for the relevant crosses. Supplemental Figure 2

Supplemental Figure 2: Relative KRAS/Kras mRNA values are similar levels in FVB, B6 and BALB strains.

Real-time quantitative PCR was performed using pancreatic RNA isolated from consomic Ela-KRAS transgenic mice. Expression values were calculated as the amount of mRNA relative to beta-actin. Each dot corresponds to one animal.
