MUC7 was the gene closest to the cut-off value (cut-off value = 0.80), suggesting that it may play a central role in the biological processes of OSCC.Furthermore, mutation analysis showed that the low-risk group exhibited lower MSI and TMB scores than the high-risk group (Fig. 7D-E) (p < 0.05), indicating a potential link between the prognostic features of RASRGs and tumor somatic mutation trends. The gene discussed is MUC7; the disease is neoplasm.
