Through further analysis of data sets from The Cancer Genome Atlas (TCGA) and Genotype‐Tissue Expression (GTEx)34, 35 of different lung tissues, including adenocarcinoma, lung squamous cell carcinoma and normal lung tissues, we verified significantly positive correlations between SDCBP and HLA‐DRB5, HLA‐DRB1, CD74, HLA‐DRA, HLA‐DPA1, HLA‐DQA1, HSP90AA1, HSP90AB1, HLA‐DPB1, HLA‐DQB1, HLA‐DQA2 and HLA‐DMA, particularly that between SDCBP and HLA‐DPB1 (Figure S3, Figure 5D‐F).36 This evidence concerns the gene HLA-DMA and squamous cell lung carcinoma.
