Multicolour fluorescence in situ hybridization (M-FISH) simultaneously dete
cts all 24 human chromosomes in unique fluorescent colours. The identificat
ion of diagnostically critical gene rearrangement(s) in complex karyotypes
of haematological disorders continues to be a challenge. We present five ca
ses in which t(9:11), complex t(8:22), t(12;21) and t(11;14) were detected
primarily using M-FISH and were confirmed using locus-specific probes. conc
lude that M-FISH can be effective in complete characterization of critical
gene rearrangements in haematological disorders.
