Among several typical cancers with great significance in the above analysis, including KIRC, PRAD, LIHC, LUSC, and BLCA, correlations between B cells and ZNF419 expression were weak or even nonexistent, but associations of ZNF419 expression with T cells were strongly positively related, either CD4+ T cells or CD8+ T cells. The gene discussed is CD4; the disease is cancer.
