An analysis published after the systematic review reported CpG sites cg06418238 in RPTOR, cg00736299 in MGRN1, and cg27466532 in RAPSN to be more commonly hypomethylated in breast cancer cases [22], although these associations were not replicated by the Melbourne Collaborative Cohort Study (MCCS) [23–25]. This evidence concerns the gene MGRN1 and breast cancer.
