Cytogenetic and molecular studies were performed on two dmin-bearing acute myelogenous leukemia (FAB-M2) samples. Both cases were characterized by complex karyotypes containing interstitial deletions of the long arm of chromosome 8 altering band 8q24. I, aberrations affecting the short arm of chromo

Gene amplification is one of the mechanisms for activating proto-oncogenes resulting in an enhanced expression of the corresponding gene product. By fluorescence in situ hybridization (FISH), amplification of the proto-oncogene MLL has been described only in seven patients with acute myeloid leukemi
## Abstract Double minute chromosomes (dmin) are small chromatin bodies consisting of genes amplified in an extrachromosomal location. dmins are uncommon in hematologic malignancies; they are seen primarily in acute myeloid leukemia, with amplification of the __MYC__ oncogene or, less frequently, t
