FGFR1 and lymphoid neoplasm: However, fluorescence in situ hybridization (FISH) confirmed the diagnosis of Myeloid/lymphoid neoplasms with FGFR1 rearrangements based on the t (8;13)(p11; q12) translocation (Figure 1A, resulting in the ZMYM2: FGFR1 fusion gene that was confirmed by Sanger sequencing (Figure 1B; Day 1 in the timeline Figure 1C).
