Rearrangements of RET are associated with thyroid cancer, such as RET/PTC1 and RET/PTC3, which are produced by fusion of RET tyrosine-kinase domain to the 5′ terminal region of coiled-coil domain containing gene 6 (CCDC6) [14] and RET/PTC3 with Ele1 [15], found in children affected by PTC after the Chernobyl accident in 1986. The gene discussed is NCOA4; the disease is thyroid gland carcinoma.
