Specially, we further used the GEPIA2 tool via matching TCGA normal and GTEx data to analyze the differential expression of WDR6 in Adrenocortical carcinoma, Lymphoid Neoplasm Diffuse Large B‐cell Lymphoma (DLBC), Acute Myeloid Leukemia (LAML), Brain Lower Grade Glioma (LGG), Ovarian serous cystadenocarcinoma (OV), Sarcoma (SARC), Skin Cutaneous Melanoma (SKCM), Testicular Germ Cell Tumors (TGCG), Thymoma (THYM), and Uterine Carcinosarcoma. The gene discussed is WDR6; the disease is testicular germ cell tumor.
