  • Title: Translocation (11;13)(q23;q14) as the sole abnormality in a childhood de novo acute myelocytic leukemia.
    Author: Tsang KS, Li CK, Lau TT, Wong AP, Leung Y, Ng MH.
    Journal: Cancer Genet Cytogenet; 2004 Apr 01; 150(1):78-80. PubMed ID: 15041229.
    Abstract:
    We report a case of childhood de novo acute myelocytic leukemia (AML) with hyperleukocytosis with monoblastic features and deranged hemostasic function. G-band karyotyping demonstrated a previously unreported t(11;13)(q23;q14) in metaphase preparations from a fluorodeoxyuridine synchronized 1-day culture of leukophoresed cells. Multicolor fluorescence in situ hybridization revealed no cryptic rearrangements except for the translocation. Reverse transcriptase polymerase chain reaction showed no concomitant positivity of AML1/ETO, BCR/ABL, PML/RARA, and CBFbeta/MYH11 resulting from t(8;21)(q22;q22), t(9;22)(q34;q11), t(15;17)(q22;q11), and inv(16) (p13q22), respectively. This report of childhood de novo AML harboring t(11;13)(q23;q14) as the sole cytogenetic abnormality provides more data on the leukemogenesis of de novo AML with a 11q23 rearrangement.
