Sluc and Scc loci identified independently in OcB and CcS strains frequently co-localize in the same donor chromosomal region.

*The ‘overlap’ chromosomal regions that have been tested for both colon cancer susceptibility in CcS RC strains and lung cancer susceptibility in OcB RC strains are listed. The regions containing a Scc gene as well as a Sluc gene are highlighted in bold.†Lung tumor susceptibility Sluc5 has been mapped in separate experiments at 87 and 100 cM, respectively (Tripodis et al. 2001); the position at 100 cM is used for the analysis.
