Vymetalkova et al. examined 13 SNPs in predicted miRNA target sites in mucin genes in 310 rectal cancer patients and the patients with CC genotype of rs4729655 in mucin 17 (MUC17) gene exhibited a longer overall survival (hazard ratio = 0.27, 95% CI = 0.14–0.54, p < 0.001) than those without CC genotype [139]. Here, MUC17 is linked to rectal cancer.
