Translocations involving chromosome band I lq23 are found in both lymphoid and myeloid leukemias as well as in lymphomas, and we have recently reported that rearrangement of the M U gene is involved in these translocations. The chromosomes most frequently involved in reciprocal translocations includ

Abstract
Here we report the case of a 7βmonthβold boy who presented with biphenotypic acute leukemia, but with leukemia cells of Bβcell phenotype present at the time of relapse. Two cell lines were derived from bone marrow specimens obtained at relapse, and immunophenotyping and analysis of antigen receptor gene configuration revealed concordance between the patient's leukemic cells and the cell lines. Cell line PERβ377 shows a new chromosomal abnormality, t(2;13)(p12;q34), a molecular rearrangement at chromosome band 11q23 in the absence of a cytogenetically detectable abnormality of this band, and deletion of the genes for IGK.

The ETV6 gene is a member of the ETS family of transcription factors and the main target of chromosomal rearrangements affecting chromosome band 12p13. To date, more than 15 fusion partners of ETV6 have been characterized at the molecular level. Most of these fusions encode chimeric proteins with on
ETV6 (TEL) is rearranged in various types of hematologic malignancies. The B-cell precursor acute lymphoblastic leukemia (ALL) cell line SUP-B2 has a t(6;12)(q23;p13) involving ETV6 at 12p13 and a submicroscopic deletion of the other ETV6 allele. The reciprocal translocation results in the fusion of
Cell killing by monofunctional methylating agents is due mainly to the formation of adducts at the O 6 position of guanine. These methyl adducts are removed from DNA by the O 6 -alkylguanine DNA alkyltransferase (OGAT). The mechanism by which O 6 -methylguanine (O 6 meG) induces cell death in OGAT-d
