-
A fusion gene that results from a translocation t(9;22)(q34;q11) that fuses the 5\' part of the BCR gene to the 5\' side of exon 2 of a mutated form of the ABL1 gene. In this fusion gene there is a point mutation where thymine has been substituted with cytosine at nucleotide position 949 of the ABL1 gene. This mutation is associated with imatinib- and dasatinib-resistant leukemias.
