Overall, these results suggest that our custom nCounter methodology could serve as a standard approach for routine biomarker testing gene fusions (NTRK1,2,3, ALK, RET (Rearranged During Transfection), ROS1 (c-ros Oncogene 1), and MET∆ex14 (Mesenchymal Epithelial Transition exon 14 skipping) in NSCLC patients. The gene discussed is NTRK1; the disease is non-small cell lung carcinoma.
