Because of similarities in involvement of the two tyrosine kinases RET (rearranged during transfection) and NTRK1 in the pathogenesis of PTC, the obvious parallels between RET and NTRK1 and between PTC and medullary thyroid carcinoma (MTC), NTRK1 seemed to be an excellent candidate gene to play a role in the genesis of MTC.
