ERBB4 and colorectal carcinoma: Considering only samples with identified fusion partners, the mean TMB was 66.6 ± 15.8 (mt/MB) for NTRK1/3+ CRC (N = 9), and 35 ± 11.5 for RET+ CRC (N = 4), which were significantly higher when compared to the mean number of 6.2 ± 5.4 of TMB for all other RTK+ CRC (ALK, EGFR, FGFR1/2, ERBB4, FLT1/3/4, LMKT2, MET, NTRK2, PDGFR‐b, ROS1) (N = 30, p < 0.05).
