Compared with the reference sequence (ENST00000555596 in Ensembl database; NR_183553 in NCBI database), LINC02820 we identified is 695 nucleotides in length, with 16 additional nucleotides at the 5′‐end and 118 additional nucleotides at the 3′‐end (Figure S2), indicating that LINC02820 we identified is a novel transcript variant in ESCC. This evidence concerns the gene LINC02820 and esophageal squamous cell carcinoma.
