CRP and rectal cancer: To see whether other non-coding SNP sites of CRP are mutated in tumors, we determined the genotypes of 3 CRP common SNPs (rs7553007, rs1205, and rs3093077) together with 21 additional SNPs in 141 tumor/normal sample pairs of 5 cancer types, i.e. gastric, lung, esophagus, colon and rectal cancers.
