The Philadelphia (Ph1) chromosome, characteristic of chronic myelogenous
leukemia (CML), arises from a reciprocal translocation between chromosomes
9 and 22. The site of the breakpoint on chromosome 22 is within a small
region called the breakpoint cluster region (bcr). We have mapped the
breakpoint within the bcr in peripheral blood leukocyte DNA from 22
Ph1-positive CML patients. No correlation between the site of the
breakpoint and the clinical phase of the disease was found. However, a
striking correlation between the site of the breakpoint and the length of
time between presentation and onset of acute phase was observed: on
average, patients with a 5' break-point had a fourfold longer chronic phase
(median, 203 weeks) than those with a 3' breakpoint (median, 52 weeks).
