Chromosomal analysis from GTG-banded metaphases revealed Ph positivity, and fluorescence in situ hybridization (FISH) with BCR/ABL dual color, dual fusion probe showed single fusion on the der(22) chromosome and ABL/BCR fusion was deleted on the der(9) chromosome.     ///    Deletion of ABL/BCR on der(9) associated with severe basophilia..     ///    The deletion (ABL/BCR) on der(9) may be associated with basophilia which may be also indicative of the transformation of CML to acute myeloid leukemia..
