NTRK1 and thyroid cancer: Richarte-Filho et al. found by analyzing the tissues from 26 Ukrainian patients from Chernobyl with thyroid cancer that were 10 years old, that 22 tumors harbored fusion oncogenes arising mainly through intrachromosomal rearrangements and 23 of the oncogenic drivers that were identified in this cohort activated abnormally the MAPK pathway, including the two somatic rearrangements resulting in the fusion of the ETV6 (ETS Variant Transcription Factor 6) gene with NTRK1 (Neurotrophic Receptor Tyrosine Kinase 1), and the fusion of AGK (Acylglycerol Kinase) with BRAF [57].
