New cytogenetic variant, insertion (15;17)(q22;q12q21), in an adolescent with acute promyelocytic leukemia
2002
We present the case of a 15-year-old female with acute promyelocytic leukemia and a new variant chromosome rearrangement identified as ins(15;17)(q22;q12q21) by conventional cytogenetic analysis. This finding was confirmed by fluorescence in situ hybridization using the PML-RARA DNA probe and whole chromosome paints 15 and 17. A typical PML-RARA fusion transcript consistent with a breakpoint in intron 3 of the PML gene and intron 2 of the RARA gene was identified by reverse transcription polymerase chain reaction.
