The RET (ret proto-oncogene) gene at 10q11 encodes for a transmembrane tyrosine kinase receptor involved in the control of cell differentiation, cell proliferation, and cell survival1.

Rearrangements involving the RET gene are recognised recurrent abnormalities seen in 1-2% patients with lung adenocarcinomas, where it is seen fused with KIF5B2,3, and papillary thyroid carcinoma where it is seen fused to a number of different partner genes including: CCDC6, PRKAR1A and NCOA44,5. The features of the proteins encoded by all types of RET fusion gene are similar to those of ALK: coiled-coil domains in the N-terminal fusion partners cause the RET domains to dimerize, resulting in activation of RET tyrosine kinase in the absence of ligands3.
