In bladder urothelial carcinoma (BLCA), breast invasive carcinoma (BRCA), kidney renal clear cell carcinoma (KIRC), brain lower grade glioma (LGG) and mesothelioma (MESO), the expression level of HNF1B also influenced the prognostic value of B-cell infiltration levels (Supplementary Figure 3). Here, HNF1B is linked to bladder transitional cell carcinoma.
