The analysis results of the correlation between the expression level of PDIA3 and MMR mismatch repair genes EPCAM, PMS2, MSH6, MSH2, and MLH1 showed that the expression level of PDIA3 was positively correlated with the expression level of MMR gene in most tumors, but it was not correlated with EPCAM gene in ACC, DLBC, and MESO, and not correlated with MLH1 in COAD and STAD, and was only strongly correlated with EPCAM gene in UCS (Figure 9(c)). The gene discussed is MRC1; the disease is adrenal cortex carcinoma.
