title: Loss of Y chromosome. An age-related event or a cytogenetic marker of a malignant clone?
abstract: Cytogenetic analysis of bone marrow cells performed at the time of diagnosis of ALL in an 80-year-old male patient revealed two unrelated abnormal clones. One included the 9;22 translocation (Philadelphia chromosome) as the sole aberration and the second was missing the Y chromosome. The significance of this finding in the light of the role of -Y clone in malignancy is discussed.
