[Application of chromosome painting technique to analysis of structural aberration of human chromosomes].
OBJECTIVE
This study was aimed at using chromosome painting technique to detect translocation, especially microtranslocations, on chromosomes in comparison with G-banding analysis.


METHODS
Chromosome painting technique was applied to analysis of metaphase chromosomes of patients for detecting translocations with biotin-labeled chromosomes X, Y, 14q, 10 specific probes.


RESULTS
Fluorescence in situ hybridization FISH signals were shown clearly in slides even in specimen stored at room temperature for 10 years and at -80 centigrade degree. Translocations were located precisely.


CONCLUSIONS
Microtranslocations, which are hard to analyze by G-banding, can be detected exactly using chromosome painting technique with G-band karyotype on metaphase chromosome.
