Here, we report a long-chain noncoding RNA AC010198.2 as a novel fusion partner of ETV6, showing a karyotype of del(12)(p13p11), with poor prognosis in a post-MPN AML that has never been reported, which may be an vital initial event in the transformation of MPN to AML and deterioration of disease. This evidence concerns the gene ETV6 and myeloproliferative disorder.
