DNAAF6 and colorectal carcinoma: We observed a marginally statistical significance between the methylation of PPP1R3F at CpG island and CRC risk (ORadj = 2.043, 95% CI: 0.971–4.297, p = 0.060), as well as the marginal association between PIH1D3 hypermethylation at a single CG site (cg 07896193) (ORadj = 1.716, 95% CI: 0.984–2.933, p = 0.057) (Table 7).
