Only Paulsson et al. have approached a detailed in-depth study of the TERT aberrancies (TPM, TERT CNV, and TERT methylation) underlying TERT upregulation in follicular thyroid carcinomas (FTC) demonstrating that TERT copy number gains, TERT methylation, and TERT expression are independently associated with FTC-related relapse. This evidence concerns the gene TERT and thyroid gland follicular carcinoma.
