Abstract:
A translocation (10;11)(p12;q14) was observed in two children, one with acute eosinophilic leukemia and the other with acute T-cell lymphoblastic leukemia. The presence of CALM-AF10 fusion was ascertained by reverse transcriptase-polymerase chain reaction (RT-PCR) analysis. Fluorescence in situ hybridization (FISH) analysis showed that AF10 gene splitting was associated with partial inversion of chromosome 11 in the first patient. In addition, FISH analysis also determined the orientation of the CALM gene, 5' telomere to 3' centromere on 11q.
