FGFR1 and myeloproliferative neoplasm: The FGFR1 gene can be fused to other genes including BCR, ZNF198, CEP110, FGFR1OP1, FGFR1OP2, HERVK, TRIM24, LRRFIP1, and MYO18A, in the 8p11 myeloproliferative syndrome manifested by myeloproliferative neoplasms and peripheral blood eosinophilia without basophilia [63]; it is fused to the FOXO1 gene in alveolar rhabdomyosarcoma, and the FOXO1-FGFR1 fusion gene is amplified [64].
