We here present the genetic and clinical features of the seventh AML case with this aberration. Materials and Methods: Cytogenetic and molecular genetic investigations were performed on leukemic bone marrow cells from a patient with therapy-related AML. Results: A t(8;19)(p11;q13) was found leading to an in-frame fusion of exon 16 of the lysine acetyltransferase 6A gene (KAT6A) from 8p11 with exon 2 of the leucine twenty homeobox gene (LEUTX) from 19q13 resulting in expression of the otherwise silent LEUTX gene in the leukemic cells. The KAT6A-LEUTX protein is predicted to act as a histone acetyltransferase at its amino-terminal-KAT6A moiety but as a homeobox transcription factor at the LEUTX-carboxyl-terminal moiety. Conclusion: The present case is the second therapy-related AML, and the third AML overall, in which both a t(8;19)(p11;q13) and its molecular result, a KAT6A-LEUTX fusion gene, are described. The t(8;19)(p11;q13)/KAT6A-LEUTX deregulates transcription and induces leukemogenesis.}, issn = {0250-7005}, URL = {https://ar.iiarjournals.org/content/41/4/1753}, eprint = {https://ar.iiarjournals.org/content/41/4/1753.full.pdf}, journal = {Anticancer Research} }
