Popp, Susanne; Jauch, Anna; Qiu, Jing Ying; Smialek, Barbara; Cremer, Thomas; Becher, Reinhard (1991): Translocation (8;21) in acute nonlymphocytic leukemia delineated by chromosomal in situ suppression hybridization. In: Cancer Genetics and Cytogenetics, Vol. 57, Nr. 1: S. 103-107


In situ suppression hybridization with recombinant bacteriophage DNA libraries for chromosomes 8 and 21 was performed in two cases of acute nonlymphocytic leukemia, type FAB M2. In both cases, cytogenetic analysis by conventional G-banding revealed t(8;21)(q22;q22). In situ suppression hybridization was able to prove the reciprocal nature of the translocation in both cases by identifying the terminal end of chromosome 21 translocated to the derivative chromosome 8q−.
