title: Translocation between chromosome 7 and chromosome 22, t(7;22)(p22;q12), in a patient with chronic myelocytic leukemia.
abstract: A 46-year-old man with chronic myelocytic leukemia had a new variant translocation between chromosome 22 and chromosome 7 in bone marrow cells. No involvement of chromosome 9 was seen. The patient entered blastic transformation within half a year, by which time he had acquired an isochromosome 17 in addition to the variant translocation.
