We also found that DLGAP5 expression was related with the CD8+ T-cell infiltration status in kidney renal clear cell carcinoma, uveal melanoma, and thymoma, and cancer-associated fibroblast infiltration was observed in breast invasive carcinoma, kidney renal papillary cell carcinoma and testicular germ cell tumors. The gene discussed is DLGAP5; the disease is testicular germ cell tumor.
