According to the association analysis for EGFR mutation in patients with adenocarcinoma (n = 108, EGFR mutant = 64), we found 159 suggestive DMPs and six significant DMPs (cg09245319, cg17183999 [USP7], cg06366994 [CPE], cg24992236 [MEG9], cg22144719, and cg22448179 [EGFR]) (Table 3). This evidence concerns the gene MEG9 and adenocarcinoma.
