The heatmap of the correlation between GNL3L and MMR showed that GNL3L is co-expressed and significantly associated with PMS2 in 32 cancers except for ESCA; GNL3L is associated with MSH6 in 28 cancers except for ESCA, LAML, UCS, DLBC, and ACC, where it is co-expressed and significantly correlated; GNL3L was co-expressed with MSH2 in 32 cancers except for UCS; GNL3L was co-expressed with MLH1 in 26 cancers except for LUSC, READ, LAML, STAD, UCS, CHOL, and MESO, which are significantly correlated (Figure 8C). This evidence concerns the gene MRC1 and cancer.
