G2E3-AS1 and neoplasm: We focused on up-regulated transcripts, as these are more likely to become implemented as a biomarker, and selected three aberrantly expressed transcripts (Figure 2A, Supplementary Table 3), namely CAT1297 and CAT1647 (the highest tumor/normal ratio based on average expression levels) and CAT266 (the highest tumor/normal ratio based on median expression levels).
