title: Late appearing 5q--marker in refractory anemia.
abstract: A patient with myelodysplasia indistinguishable from the 5q--syndrome is described. No clonal chromosome abnormalities were detected in the total of 120 bone marrow cells initially examined. At the next sampling, 3 years later, del(5q) was present in all analyzed metaphases. These findings indicate that del(5q) may be only one of the pathogenetically important events in the 5q--syndrome, and that submicroscopic changes may precede the visible chromosomal rearrangement.
