THRB and neoplasm: To further analyze the predicted IM subtype association with immune features, we derived Shannon–Wiener diversity indexes for TCR genes (TCR: TRA, TRB, TRD, and TRG) and B-cell receptor (BCR) genes (BCR: IGH, IGK, and IGL) based on TCR/BCR repertoire analysis of available bulk tumor RNA-seq data in the SCAN-B_validation and FUSCC_validation cohorts.
