Cytogenetics of three cases of ANLL M2 and M4. Involvement of chromosomal region 8q22 in all three but 21q22 in only one.
Cytogenetic investigation of the bone marrow of two patients with acute nonlymphocytic leukemia (ANLL), French-American-British Cooperative group (FAB) classification M2, revealed a translocation (8;22)(q22.1;q13.3), without involving chromosome 21, and a variant translocation (8;21)(q22;q22). These findings, together with a del(8)(q22) found in a patient with refractory anemia, erythroblastic (RAEB)-t with progression to acute myelogenous leukemia (AML)-M4, are discussed in relation to the possible role of abnormalities of chromosomes 8 and 21 in the oncogenesis of ANLL M2 and M4.
