A further case of acute myelomonocytic leukemia with inv(8) chromosomal rearrangement and MOZ-NCOA2 gene fusion.
We report here the sixth case of acute monoblastic leukemia associated with the inv(8)(p11q13) pericentric inversion. As seen in the previous cases, the inv(8)(p11q13) molecular characterization showed that the alteration results in a MOZ-NCOA2 gene fusion. The presence of erythrophagocytosis is a distinctive morphologic feature that is observed in all patients with MOZ alteration. However, the relative young age of the 6 patients (median: 23.5 years) and same sex (female) are the common characteristics that are only observed in the inv(8)-positive leukemia subgroup. In addition, we tested whether the presence of FLT3 internal duplications (ITD) are frequently found in malignant hemopathies with 8p11-12 rearrangements. We did not find any FLT3 ITD in any of the studied cases.
