Chromosome 16 aberrations are well known in acute nonlymphocytic leukemia
(ANLL). The most frequent chromosome 16 aberration in ANLL subtype M4Eo is
the inv(16)(p13q22). Recently, we showed that in 5 inv(16) patients with
ANLL M4Eo the short arm breakpoints are clustered within a 14-kb genomic
EcoRI fragment. We report here the identification of a gene situated in the
14-kb fragment. The gene, which codes for a myosin peptide, is disrupted by
the inversion of chromosome 16 in the 5 patients. To the best of our
knowledge, this is the first report of a myosin gene disrupted in leukemia.
