Thus, we performed a pan-cancer expression analysis of MITD1 in 33 cancer types using The Cancer Genome Atlas (TCGA), Tumor Immune Estimation Resource (TIMER), and Human Protein Atlas (HPA), including data on MITD1 expression, clinical survival prognosis, TME, TMB, MSI, HRD, and ploidy. The gene discussed is MITD1; the disease is neoplasm.
