Chromosomal anomaly of 6q in chronic myelogenous leukemia (CML).

Anomalies of chromosome 6q, along with other chromosomal anomalies, are described in the bone marrow cells of two patients with chronic myelogenous leukemia (CML). One patient a 14-year-old male, developed the karyotype 46,XY,t(1;6)(p36;q15),del(3)(q25), del(17)(p11),? inv(17)(q12q24) during blastic crisis of his disease. The other patient, a 24-year-old male, had the karyotype 46,XY,del(6)(q13),5(9;22)(q34;q11) during the early phase of his disease and evolution of i(17q) in the karyotype late in the disease.
