Inappropriately rearranged IgH or TCR genes are usually not expressed at the mRNA level, and the gene for the TCR associated protein T3 delta is not detectably expressed at the mRNA or protein level in leukemias classified unambiguously as non-T. Five cases of acute leukemia with ambiguous or mixed lineage immunophenotypes (myeloid + T or myeloid + B) are described.

Our cytogenetic analysis of one such cell line, SUP-T3, demonstrates that the breakpoints on chromosomes 7 and 9 lie within bands q36 and q34, respectively, corresponding to the location of the gene encoding the beta chain of the T-cell receptor, TCRB, and the gene homologous to the transforming gene of the Abelson murine leukemia virus, ABL.
