rs4939827 is one of 3 SNPs in the SMAD7 gene associated with risk for colorectal cancer, based on a large study (7,400+ cases) conducted in the UK. The odds ratios show a decreased risk for the minor rs4939827(C) allele; the OR for (C;C) homozygotes is 0.73 (CI: 0.66-0.8), and for (C;T) heterozygotes 0.86 (CI: 0.79-0.92), overall p=1x10-12.[PMID 17934461]
