Acute myeloid leukemia (AML) carrying inversion or translocation of chromosome 16 is usually associated with the FAB M4Eo morphological subtype and belongs to AMLs with a relatively favorable prognosis. At the molecular level, it is associated with a disease-specific fusion gene, CBFbeta/MYH11. Previously, 10 different types of CBFbeta/MYH11 fusion transcripts have been described in the literature, 7 of them are still known as unique cases. In the current study, peripheral blood and/or bone marrow samples from 265 AML patients were tested for the presence of the CBFbeta/MYH11 fusion using RT-PCR and 12 (4.5%) positive cases were identified. The most common type A CBFbeta/MYH11 transcript was confirmed in 11 patients. The transcript in the remaining one (a 71-year-old female) was different and sequence analysis allowed us to classify it as CBFbeta/MYH11 type J. In contrast to the first type J case previously reported from Australia, this patient exhibited a typical FAB M4Eo morphology. The evidence of the second case indicates that the type J breakage might be a non-random event within the MYH11 gene.
