The nuclear enzyme terminal deoxynucleotidyl transferase (TdT) is thought to contribute to the diversity of certain immunoglobulin and T cell receptor gene rearrangements through the addition of random nucleotides at their variable (V)-joining (J) region junctions. An acute lymphoblastic leukemia (ALL) with an immature T cell phenotype (CD7+, CD5+, CD1+/-, CD2+/-, CD3-, CD4-, CD8-) was found to be TdT+ with germline immunoglobulin heavy chain, T cell receptor beta chain, and T cell gamma chain genes. The data indicate that TdT expression can precede T gamma and T beta rearrangement during T lymphoid ontogeny consistent with its proposed association with the T cell receptor rearrangement process. Southern analysis of certain cases of T-ALL may not result in the detection of a monoclonal population of cells.

We have used probes from the T cell receptor beta and gamma chain loci to investigate the clonality of T lymphocytes in eight patients with T cell lymphocytosis and cytopenia (TCLC). This syndrome, which is strongly associated with rheumatoid arthritis, is characterized by peripheral blood and bone marrow lymphocytosis and neutropenia, red cell aplasia, or both. By means of T cell monoclonal antibodies and flow cytometry, T lymphocytes from patients with this syndrome have been shown to have characteristic immunologic features. Investigators have disagreed as to whether the syndrome represents a T cell malignancy or a more benign immunologic disorder. DNA from five of five patients with symptomatic “classic” T cell lymphocytosis with cytopenia demonstrated unique rearrangements of the T cell receptor beta chain locus, whereas neither of two patients with atypical features showed rearrangement. In addition, we found evidence for gamma chain rearrangement in those DNAs with clonal beta chain rearrangement. We thus postulate that the classic form of this syndrome is associated with a monoclonal proliferation of T cells. Its potential relationship to T cell chronic lymphocytic leukemia is discussed.
