Acute myeloid leukemia (AML) is characterized by chromosomal abnormalities affecting both prognosis and course of treatment. While most AML patients have well described chromosomal aberrations, around 10% present with rare chromosomal abnormalities. We herein, report a rare balanced translocation t(12;19)(q13;q13) in a 66-year old M5-AML patient identified by Conventional cytogenetic analysis and confirmed by SNP array. We suggest that t(12;19) as a sole chromosomal abnormality could be associated with a poor prognosis. Further studies are needed to understand the molecular basis of this translocation in AML.
