By analyzing the expression of HRD and HNRNPA2B1 in pan-cancer samples, we found that they were significantly correlated in 17 tumors, with significant positive correlation in 16 tumors, such as GBMLGG, LUAD, LGG, BRCA, STES, SARC, KIPAN, STAD, PRAD, HNSC, KIRC, LUSC, LIHC PAAD, BLCA, and ACC, and significantly negatively correlated in one tumor: THYM (Figure 6(j)). The gene discussed is TBCE; the disease is neoplasm.
