Abstract

It has recently been reported that additional X chromosomes occur in over 30% of B-cell non-Hodgkin's lymphomas (NHL), and that monosomy of the X chromosome occurs in 38% of female patients with T-cell leukaemia or lymphoma. These observations have suggested a possible role for the X chromosome in the evolution of NHL. We have now examined 280 cases of NHL, and have identified 19 examples of structurally altered X chromosomes in the malignant cells from 17 of these cases. These abnormalities were mainly characterized by either a translocation involving Xp22, or a translocation/deletion involving Xq28. The relevance of these observations is discussed with respect to other published reports, and together they suggest that lymphoma-associated oncogenes may exist on the X chromosome at bands p22 or q28.
