GIST genetic profiles were reported as KIT mutation 69%, PDGFRA mutation 6%, SDH deficient 8%, NF1 associated 4%, ETV6-NTRK3 (translocation-Ets-leukaemia virus and neurotrophic tyrosine kinase, only tested in one of the WT patients) gene fusion 2%, quadruple WT 6%, triple WT 2% and KIT/PDGFRA WT 2%.
