The RET (rearranged during transfection) proto-oncogene is mapped to human chromosome 10q11. It has two isoforms, namely RET9 and RET51 with unique C-terminal tail sequences. RET is made of 20 exons and 21 introns.
The RET (rearranged during transfection) is involved in signal transduction pathways related to cell proliferation and differentiation. Mutations in RET gene results in medullary thyroid carcinoma and Hirschsprungμs disease. It is involved in normal development and cancer. The isoforms of RET provides distinct protein complexes to promote signals.
