Abstract
We describe a patient with chronic myeloid leukemia (CML) and a 22qβ but no 9q + chromosome. Southern blot analysis showed a BCR rearrangement. The patient soon developed profound and superficial thrombophlebitis in arms and legs and died from pulmonary embolisation 15 days after diagnosis. Five CML cases with a deletion of 22q but no known translocation of 22qll β qter have been described earlier. The present patient is the first such case, however, in whom a BCR rearrangement has been demonstrated.

## Abstract Leukemic cells from two patients with Philadelphiaβnegative chronic myeloid leukemia (CML) were investigated: I) Cytogenetics showed a normal 46.XY karyotype in both cases, 2) molecular studies revealed rearrangement of the MβBCR region and formation of __BCRβABL__ fusion mRNA with b2a2
Two new variant Philadelphia (Ph) chromosomes with an aberrant location of the BCR-ABL fusion gene on 9q34 of the derivative 9 are reported. One presented cytogenetically as a standard t(9;22)(q34;q11), whereas the other was classified as an ins(9;22)(q34;q11.1q11.2) using the combined interpretatio
