As a single gene, MS4A1 mRNA levels alone were prognostic in seven cancers (UVM, LGG, KIRP, colon adenocarcinoma (COAD), LUAD, HNSCC, and CESC), while TIL-B levels alone were prognostic for nine cancer types (LGG, DLBC, KIRP, breast invasive carcinoma (BRCA), HNSCC, LUAD, uterine corpus endometrial carcinoma (UCEC), THYM, and CESC; Fig. 1d). The gene discussed is MS4A1; the disease is head and neck squamous cell carcinoma.
