Of the two other patients with CRC, one had a tumor harboring a GABRG1::NTRK3 fusion, and the other had a tumor harboring the NTRK2 gene with two different fusion partners identified from one sample – FXN and LPPR1. Five of these eight patients with CRC had tumors tested for MSI with four mismatch repair proteins (MLH1, MSH2, MSH6, and PMS2). Here, FXN is linked to colorectal carcinoma.
