Multiple chromosomal changes and karyotypic evolution in a patient with myelofibrosis.
Several subclones were identified in unstimulated peripheral blood cells from a patient with chronic myeloproliferative disease, which was classified as myelofibrosis by morphologic terms. These subclones were characterized by an unusual number of different karyotype anomalies. Some of the more complex chromosomal rearrangements could be clearly defined by fluorescence in situ hybridization. Chromosome arms involved in clonal aberrations were 1q, 3p, 6p, 7q, 11q, 13q, 15q, 17q, 18p, and 20q. Reconstruction of karyotype evolution was attempted by karyotypic analysis of 100 metaphase spreads each in two separate investigations.
