The ETV6 gene, located at chromosome 12p13, belongs to the ETS family of transcription factors, which share a conserved 80 amino acid DNA-binding domain, the ETS domain (1). It encodes an essential transcriptional repressor that is abundantly expressed in hematopoietic stem and progenitor cells (HSPCs). It is critical for the maintenance of HSPCs and the formation of platelets (2, 3), and has been shown to be closely associated with inherited thrombocytopenia and leukemia predisposition (3, 4). ETV6 variants include insertion/deletion mutations and structural variants (deletions, rearrangements) that may lead to truncation and loss of function of ETV6, ultimately contributing to thrombocytopenia and leukemia (4). It has been reported that ETV6 has over 30 partner genes (Supplementary Table 1), such as PDGFRB (1), RUNX1 (5), ACSL6 (6) and non-protein coding RNA like LINC02260 (7) and so on, and is one of the most common translocation genes in acute lymphoblastic leukemia (ALL), as well as other hematological disorders, such as acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) (1). Functional investigations of ETV6 variants have shown that they are associated with disrupted expression of genes involved in platelet production and platelet cytoskeleton dynamics, including genes CDC42 and RHOA218, but the mechanisms driving leukemia remain unclear (4). Recent studies have shown that ETV6 is required to repress inflammatory gene expression in hematopoietic stem/progenitor cells (HSPCs), and this mechanism may be critical for maintaining HSPCs function (8). Here, we report a long-chain non-coding RNA
