TUBA1B and non-small cell lung carcinoma: A three‐step, trans‐omics study identified two gene–gene interactions, cg14391855 × cg23937960 (mapped to RELA × HLA‐G) as well as cg08872738 × cg27077312 (mapped to TUBA1B × TOMM40), which were significantly and robustly associated with NSCLC survival at both the epigenetic and transcriptional levels.
