The bone marrow chromosomes of 24 patients with Philadelphia positive (Ph 1) chronic granulocytic leukaemia (CGL) were studied using banding techniques. In 23 patients, the Ph(1) had been produced by the standard translocation between chromosomes 9 and 22, but in the remaining patient, the Ph(1) chromosome had been formed by a translocation between chromosomes 16 and 22. Clinical and haematological details of this patient are reported.
