We report a case of acute nonlymphocytic leukemia (ANLL) M5 with the
characteristic t(8;16)(p11;p13). The breakpoint in the short arm was
regionally localized using nonradioactive in situ hybridization with a
series of cosmids of chromosome 16. The results show that a difference
exists between the breakpoint in chromosome 16(p13) in this t(8;16) and the
breakpoint involved in the short arm in the characteristic inversion 16
(p13;q22)) that occurs in ANLL M4eo. Two different loci appear to be
involved in these chromosomal rearrangements.
