Analyses performed to study possible changes in gene expression associated with rs6687758 in tumour versus normal colon tissue showed that gene DUSP10 is more expressed in colon sigmoid tissue when rs6687758 has GG genotype (in healthy individuals) (S1 Fig), but also, that it has higher expression in cases of colon and rectum adenocarcinomas than in healthy persons (S2 Fig). Here, DUSP10 is linked to rectum adenocarcinoma.
