PLCG2 and colorectal carcinoma: An excellent diagnostic performance of PLCG2 was demonstrated in BRCA (0.836, 95%CI: 0.807-0.865), COREAD (0.917, 95%CI:0.888-0.946), GBM (0.803, 95%CI:0.771-0.835), and KICH (0.929, 95%CI:0.878-0.981) respectively, as shown in Figure 1D. We then explored the expression of PLCG2 in CRC at the protein level.
