Stratified analysis by histological lesion revealed the association of rs10505477 and rs6983267 variants with reduced risk of low- and high-risk adenomas in controls, being this effect stronger in low-risk adenomas (log-additive models, OR:0.63, 95%CI:0.47-0.84 and OR:0.64, 95%CI:0.47-0.86, respectively).
The CRC SNPs accounted for 4.3% of the variation in multiple adenoma risk, with three SNPs (rs6983267, rs10795668, rs3802842) explaining 3.0% of the variation.
The strength of the association of the regional haplotype containin</span>g variant alleles at rs10808555, rs6983267</span> and rs7837328 but not rs10505476 was greater than that of any single variant of both adenoma (OR = 1.27, P = 0.0001) and cancer (OR = 1.26, P = 0.03).
