Our study revealed that MITD1 expression was positively correlated with the immune score in GBMLGG, LGG, BRCA, KIPAN, PRAD, KIRC, BLCA, SKCM-M, and DLBCL but negatively correlated with the immune score in COAD, COADREAD, LUSC, WT, and OV. This evidence concerns the gene MITD1 and diffuse large B-cell lymphoma.
