[Oncogenes and malignant hemopathies].

In the last ten years molecular biology has defined the role of oncogenes in the pathogenesis of malignant blood diseases. Included among these are: chronic myelogenous leukemia, with abl oncogene; Burkitt's lymphoma, where myc oncogene is translocated from chromosome 8 to chromosomes 2, 14 or 22 near immunoglobulin genes; some acute myelogenous leukemias; myelodysplastic syndromes with deletion of the long arm of chromosome 5.
