title: Translocation 5;21 and interstitial deletion of chromosome 7 in a case of chronic myelomonocytic leukemia.
abstract: We report a case of chronic myelomonocytic leukemia with a translocation involving chromosome 5 and 21, namely, t(5;21)(q35.3;q22.1), and an interstitial deletion of the long arm of chromosome 7. High-resolution analysis at the 900-band stage has shown that the lesion in chromosome 7 is an interstitial deletion involving loss of the segments q22-q35 of the long arm of chromosome 7 and retaining the telomere.
