  • Title: Acute lymphoblastic leukemia with the (4;11) translocation: combined cytogenetic, immunological and molecular genetic analyses.
    Author: Schardt C, Ottmann OG, Hoelzer D, Ganser A.
    Journal: Leukemia; 1992 May; 6(5):370-4. PubMed ID: 1375695.
    Abstract:
    Five cases of acute leukemia (AL) with the t(4;11) translocation were investigated for the immunoglobulin heavy chain, kappa, lambda, TCR beta and TCR gamma gene rearrangements. All patients presented with high-risk features and had survival times of less than two years. Two cases were classified by immunological phenotyping as acute null-AL(L), one case as pre B-cell ALL (CD10+) and two cases expressed both immature B-cell markers CD19 and CD24 and myelomonocytic markers CD15 and CD14, suggesting mixed lineage leukemia. In two cases more than two rearranged fragments for the immunoglobulin heavy chain gene could be detected by Southern blot analysis. In the other cases at least one allele of the immunoglobulin heavy chain gene was rearranged. Germline configuration of the T-cell receptor genes and lack of light chain gene rearrangement suggest that an early B-precursor cell is involved in the transformational events in these cases of ALL. Our own and published data indicate that acute leukemia with t(4;11) translocation might be more frequently associated with more than two rearranged fragments for the immunoglobulin heavy chain genes and run a very aggressive course.
