In total, ten aberrantly methylated and dysregulated genes (AURKA, BLK, CNTN2, HMGA1, PTTG1, TNS4, DAPK2, MFSD2A, THSD1, and WNT7A) were highlighted which were significantly correlated with overall survival of 492 LUAD patients, which were all reported as tumor‐associated genes in other various cancers and worthy of further investigated and might be used as therapeutic targets for LUAD. This evidence concerns the gene DAPK2 and neoplasm.
