ABSTRACT
Chronic myelogenous leukaemia is a clonal neoplasm of the pluripotent haematopoietic stem cell which is characterized in most patients by a consistent cytogenetic abnormality known as the Philadelphia chromosome. This chromosome occurs as a consequence of a reciprocal translocation between the long arms of chromosomes 9 and 22 which results in the creation of a new gene comprising sequences from the c-abl gene on chromosome 9 and the bcr gene on chromosome 22. The protein encoded by this structurally altered hybrid gene differs from the normal c-abl gene product in both molecular weight and in tyrosine kinase activity. It is likely that these alterations in the c-abl gene product play a central role in the pathogenesis of this leukaemia.
