in situ
hybridization (FISH) to assess the presence of structural
rearrangement and numerical chromosome aberrations in both metaphase chromosome and inter-
phase nuclei. For this purpose, the biotinylated repetitive alpha-satellite DNA probes for chro-
mosome I, 18 and 8 (pUCI.77, LI.84 and pJM128) were used to identify tetraploid mosaicism,
ring chromosome 18 and trisomy 8 mosaicism for pre-, post-natal and tumor diagnosis res-
pectively. Utilizing this approach, we showed the usefulness of FISH for routine clinical cyto-
genetics in addition to chromosome banding techniques. The chromosome aberrations with
unknown or unclear origin, detected by chromosome analysis, could be confirmed accurately
and rapidly.
