(a) Karyotype from a bone marrow specimen at the time of chronic myeloid leukemia (CML) diagnosis. t(9; 22) is shown by using arrows. (b) Fluorescence in situ hybridization for peripheral blood cells. Arrowheads, BCR-ABL fusion gene (yellow); large arrows, ABL signal (red); small arrows, BCR signal (green). (c) Polymerase chain reaction (PCR) amplification analysis from the bone marrow specimen taken at the time of CML diagnosis. Lane 1, size marker; lane 2, p210 negative control; lane 3, p190 negative control; lane 4, p210 positive control; lane 5, p190 positive control; lane 6, p210 patient’s sample; lane 7, p190 patient’s sample.
