Objective To evaluate the feasibility of using fluorescence
in situ
hybridization for the detection of a few common chromosome aneuploidies on interphase nuclei of uncultured amniotic fluid cells. Methods A total of 50 patients with indications of chromosome aneuploidies underwent amniocentesis or cordocentesis with karyotyping. Simultaneously
interphase FISH with X
Y
13
18 and 21 chromosome-specific probes was done on them. Results Each of the 50 uncultured amniotic fluid samples tested with FISH was enumerated 50 nuclei. Forty-seven samples were normal and three samples were found to have trisomy 21. The results were accordant with the chromosome karyotype analysis and the follow-up survey. Conclusion FISH analysis of chromosome-specific probes on interp
hase amniocytes can be used in the prenatal diagnosis of chromosome aneuploidies. This is a rapid
accurate and very sensitive method and can be used in clinical diagnosis.
