Among the DMRs identified in this study for dietary folate or alcohol intake, several regions were associated with genes potentially implicated in cancer development, such as RTKN, the HOX family of genes, and the two tumor suppressor genes GSDMD and TSPAN32. Our study provides some evidence that dietary folate and alcohol intakes may be associated with carcinogenesis through a deregulation of epigenetic mechanisms, although our findings need to be replicated in future evaluations. The gene discussed is RTKN; the disease is cancer.
