title: Involvement of chromosomal region 9q34 in a case of variant Ph1 translocation t(22;22).
abstract: In a patient with chronic myelocytic leukemia chromosome analysis showed a translocation (22;22) (q13;q11). Chromosomes 9 were apparently not involved. Using somatic cell hybrids and a v-abl probe, we demonstrated the translocation of c-abl sequences from chromosome 9 to chromosome 22q-. This confirms the hypothesis that the translocation of c-abl oncogene is essential for the development of Ph1 positive CML.
