In‐line with these studies, our co‐FISH results of TERT‐locus and the subtelomeric‐end of chromosome 5p showed that telomere length determines conformation differences at this subtelomeric region, supporting that telomere shortening leads to a more relax or transcriptionally active conformation of chromosome 5p‐end in thyroid cancer. Here, TERT is linked to thyroid gland carcinoma.
