NCIt definition : A fusion gene that results from a chromosomal insertion ins(12;8)(p11;p11p22) that
fuses exon 4 of the FGFR1OP2 gene with exon 9 of the FGFR1 gene. This translocation
is associated with 8p11 myeloproliferative disorder.;
NCIt note : Since the direction of FGFR1OP2 transcription is in the opposite orientation to the
direction of FGFR1 transcription, an inversion must have taken place during the formation
of the chimeric gene. (OMIM);
