Paradoxically, other genes, such as TERT, represent an exception to this regulation, as some authors reported that TERTp hypermethylation correlates with TERT overexpression in telomerase-positive cells [72,415,427,428], while the absence of TERT methylation was reported in some TERT-negative tumours and TERT-negative normal cells [28,72,429]. Here, TERT is linked to neoplasm.
