With multiprobe FISH panel, 22 of the 40 AML cases were found to carry 7 types of cytogenetic abnormalities, namely AML1/ETO transfusion gene, PML-RAR? transfusion gene, MLL breakapart, P53 deletion, Del(5q), -7/Del(7q) and trisomy 8.     ///    "The multiprobe AML/MDS panel comprising 8 different FISH probes for AML1/ETO transfusion gene, PML-RAR? transfusion gene, CBF?/MYH11 transfusion gene, MLL breakapart, P53 deletion, Del(5q), -7/Del(7q), and Del(20q) was tested in 40 cases of AML, and the results were compared with those by conventional cytogenetic G-banding (CCG) test.
