Then, we calculated and compared the transcriptional expression of significant mismatch repair genes in tumor samples and found that all four mismatch repair genes (MLH1, MSH2, MSH6, and PMS2) expressed significantly higher in the high-risk group (Figure 11C–F), which signified that the microsatellites might be more stable in the high-risk group. The gene discussed is PMS2; the disease is neoplasm.
