Furthermore, FGFR1 has been implicated in the tumourigenesis of haematological malignancies, where it is frequently involved in balanced chromosomal translocations, including cases of chronic myeloid leukaemia (BCR-FGFR1 fusion) and the 8p11 myeloproliferative syndrome/stem cell leukaemia–lymphoma syndrome, which is characterised by myeloid hyperplasia and non-Hodgkin's lymphoma with chromosomal translocations fusing several genes, the most common being a fusion between ZNF198 and FGFR1 [32]. This evidence concerns the gene BCR and chronic myelogenous leukemia, BCR-ABL1 positive.
