As discussed in what follows, we also successfully analysed the genome of 401 cases for copy number alterations, revealing that all cases with TERT promoter hotspot mutations (n = 180) were mutually exclusive from high‐level amplifications of TERT (n = 15), except for a single high‐mutation‐load tumour (supplementary material, Figure S3D). Here, TERT is linked to neoplasm.
