Among the top 20 upregulated (Supplementary Fig. S7) and downregulated genes (Supplementary Fig. S8), the expression levels of four genes (GSTM1, KRT20, CNNM1, and RYR2) upregulated in BAA HNSCC were positively associated with OS in these patients, but not in Whites (Fig. 5D-E). The gene discussed is KRT20; the disease is head and neck squamous cell carcinoma.
