Chronic myelogenous leukemia with translocations (3q-;9q+) and (17q-;22q+). Possible crucial cytogenetic events in the genesis of CML

Two reciprocal translocations involving chromosomes 3, 9, 17, and 22 were found in a patient with seemingly Ph¹-negative chronic myelogenous leukemia (CML). The two translocations were t(3;9)(q21;q34) and t(17;22...
