ATM and thyroid cancer, nonmedullary, 2: Intersection of the differentially expressed lncRNAs and subsequent comparison of the expression between subtypes of neoplasms led to the discovery of lncRNAs common to FA and WDTC (13 genes), common to WDTC (6 genes), common to classical and follicular variants of PTC (22 genes), and specific to FTC (19 genes), fvPTC (1 gene), clPTC (32 genes), and ATC (185 genes).
