ABSTRACT
OBJECTIVE@#To carry out multipath cytogenetic analysis of a rare case of acute myeloid leukemia (AML) with 11q23 aberration and D13S319 deletion.@*METHODS@#G+R banding technique was used to analyze the chromosomal karyotype of the patient after 24 h of cell culture. Combined interphase and metaphase fluorescence in situ hybridization (FISH) was used to detect specific chromosomal sites for complex translocations and minor missing fragments.@*RESULTS@#The patient was found to harbor MLL-AF10 fusion gene due to rearrangement of the mixed lineage leukemia (MLL) gene in conjunct with deletion of the D13S319 locus on chromosome 13.@*CONCLUSION@#Whether MLL gene rearrangement and absence of D13S319 locus has a double impact on AML should attract more attention. For AML patient with clonal abnormalities such as 13q-, del(13)(q14), -13 or der(13), FISH assay should be proof and considered to determine the size of missing fragment so as targeted therapy may be implemented.
