According to the company, the Seraseq NTRK FFPE RNA reference material contains 15 clinically significant NTRK RNA fusions across NTRK1, NTRK2 and NTRK3
genes and are to be used by clinical laboratories looking to validate their detection by next-generation sequencing (NGS) methods.
Another set of patients demonstrate translocation involving tyrosine kinases, such as ABL1 (with genes other than BCR), ABL2, PDGFRB, NTRK3
, TYK2, CSF1R, and JAK2.
ETV6 is genetically unstable and fuses not only with NTRK3
but also with other genes, including ABL1, EGFR3, PAX5, SYK and JAK2 in leukaemia, myelodysplastic syndromes, and sarcomas (7).

Esta enfermedad se puede generar por herencia genetica o por radiacion, y se ven afectados genes como: RET, BRAF, RAS, EIF1AX, PPM1D y CHEK2 y translocaciones que afectan PPARg, NTRK1, NTRK3
, THADA y FGFR2, ademas de alteraciones moleculares como cadherina epitelial, molecula neural de adhesion celular (N-CAM), p-catenina, p53 y p63 [1,3].
