Abstract

A patient with acute nonlymphocytic leukemia (ANLL), M5b according to French-American-British (FAB) classification, showed monosomy 16, an extra 1p−, and a 21q+. These derivative chromosomes could not be defined by GTG-banding. For better characterization, we performed two-color fluorescence in situ hybridization (FISH) experiments applying DNA libraries from sorted human chromosomes, chromosome-specific repetitive probes, and a band-specific YAC-clone. With these FISH studies the karyotype could be characterized as 46,XY,+der(1)t(1;21)(p11;?),−16,der(21)t(16;21)(p11.1;q22).
