In addition, high expression of COMMD6 was associated with longer OS in patients with testicular germ cell tumours (TGCT, P = 0.05, HR = 1.7E-09), longer DFS in patients with thyroid carcinoma (THCA, P = 0.017, HR = 0.48) and uterine corpus endometrial carcinoma (UCEC, P = 0.029, HR = 0.47) (Fig. S6E–G). Here, COMMD6 is linked to thyroid gland carcinoma.
