Novel germline RET mutation segregating with papillary thyroid carcinomas

Abstract

The RET proto-oncogene is responsible for inherited medullary thyroid cancer syndromes. RET is also found mutated in sporadic medullary thyroid cancer (MTC) and rearranged in sporadic papillary thyroid carcinomas. Here, we describe a previously unreported germline RET mutation at codon 603 in exon 10 associated with both MTC and nonmedullary thyroid cancer (NMTC) in a kindred. RET may thus not be excluded as a potential candidate for predisposition to some forms of NMTC. © 2001 Wiley-Liss, Inc.
