SLC31A1 and testicular germ cell tumor: Worse OS was found to be associated with higher SLC31A1 expression in adrenocortical carcinoma(ACC) (P = 0.0012), BRCA (P = 0.0027), mesothelioma (MESO) (P = 1.8 × 10–5), Skin cutaneous melanoma (SKCM) (P = 0.027), LGG (P = 0.00012), Testicular germ cell tumors (TGCT) (P = 0.05), and Thymoma (THYM) (P = 0.038), and associated with lower SLC31A1 expression in KIRC (P = 3.5 × 10–5) in 5 years (Fig. 2).
