More than 70% of mouse autosomes carry solid tumor susceptibility loci for the small intestine and colon. Mouse chromosomes are shown with centromeres at the top. Positions of susceptibility loci were based on the marker at the peak of the interval. All Mb positions are derived from the Ensembl database (release 61, April 2007) (NCBI m37) (http://www.ensembl.org). With the exception of the Mom14–18 reported here, the remaining loci were previously reported (11,15,16,21,23,33,35,49–62). Mom3, Mom6, Mom12, Scc2-15, and Ssic1 loci are shown ±5Mb from the peak marker. The chromosomal location of Mom13 is unknown.
