As shown in Figure 2(a), high expression of KLRB1 was associated with a better prognosis in most cancers, including adrenocortical carcinoma (ACC) (p = 0.009), BRCA (p < 0.001), cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC, p < 0.001), HNSC (p < 0.001), LIHC (p = 0.004), LUAD (p = 0.002), mesothelioma (MESO, p = 0.015), ovarian serous cystadenocarcinoma (OV, p = 0.024), sarcoma (SARC, p = 0.010), skin cutaneous melanoma (SKCM, p < 0.001), THCA (p = 0.049), and UCEC (p < 0.001), while KLRB1 was a high-risk gene in uveal melanoma (UVM, p = 0.009). The gene discussed is KLRB1; the disease is cutaneous melanoma.
