The emergence of well-differentiated thyroid tumors such as papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC) has been linked to alterations in various genes, including BRAF, RAS, and RET, and recently discovered gene fusions, such as EIFIAX, RET, NTRK1/3, ALK, PAX8-PPARG, RGADA, FGR2, and LTK [2]. The gene discussed is RET; the disease is thyroid tumor.
