The t(9;22) is diagnostic of CML in the appropriate morphology and clinical context (add reference). This fusion is responsive to targeted therapy such as Imatinib (Gleevec) (add reference). BCR::ABL1 is generally favorable in CML (add reference).
 
 
This fusion suggests abnormal FGFR2 expression. Aberrant The ''FGFR2'' activation resulting from ''ETV6::FGFR2'' may respond to ''FGFR1,2,3'' tyrosine kinase inhibitors (TKIs). <ref>{{Cite journal|last=Katoh|first=Masaru|date=2019-02|title=Fibroblast growth factor receptors as treatment targets in clinical oncology|url=https://pubmed.ncbi.nlm.nih.gov/30367139|journal=Nature Reviews.
