Specifically, 1/107 (0.9%) PTCs displayed four copies of TERT; while 2/22 (9%) FTCs, 4/29 (13.8%) HCCs, 0/22 (0%) MTCs, and 2/4 (50%) PDTCs/ATCs harbored three copies of TERT. In addition, one HCC and one PDTC/ATC with 3 copies of TERT also harbored the TERT −124 C>T mutation (65). Here, TERT is linked to hepatocellular carcinoma.
