Chronic myelogenous leukemia (CML) is characterized by a reciprocal translocation between chromosomes 9 and 22. The breakpoints on chromosome 22 are clustered within a 5.8-kilobase (kb) DNA fragment known as the breakpoint cluster region (bcr), which encodes part of a functionally active gene. We analyzed the bcr in DNAs from 108 consecutive, unselected Philadelphia chromosome-positive CML patients by Southern blot and determined five restriction enzyme fragments within which breaks occur on chromosome 22. The exact sublocalization was determined in the DNA of 100 patients. It was found to be within the 5.8-kb in 99 patients and outside the bcr in only one. Within the bcr, most of the breakpoints occurred in fragments 1, 2, and 3. Overall, laboratory and clinical features of CML did not correlate with specific breakpoint fragments, but chronic-phase duration was longer in patients with a breakpoint in fragment 2 of the bcr. Large 3' bcr deletions were found in nine patients but did not influence clinical outcome. DNA from one of six patients analyzed both during chronic phase and blastic crisis showed an additional aberrant fragment, which suggested that a second abnormal clone developed in blastic crisis.
