The patterns of RET proto-oncogene expression in mouse, rat, and chicken and the anomalies observed in targeted RET mutants suggest that RET plays a major role in development of mouse enteric nervous system and in kidney organogenesis. Here, we report on in situ hybridization studies describing the

✦ Synopsis
Medullary thyroid carcinoma (MTC) may occur sporadically or as part of the autosomal dominant multiple endocrine neoplasia type 2 (MEN 2). Three hereditary forms of MEN 2 have been identified: MEN 2A, MEN 2B, and familial MTC (FMTC). Missense germ-line mutations in the RET protooncogene have been identified as cause of these endocrine diseases. Mutations are found in exons 10 and 11 in MEN 2A and FMTC families and in a small number of families in exons 13, 14, and 15. Although a strong correlation between codon mutations and phenotypes has been described, not all the expected cystein codon mutations have been found. Therefore, the more mutations are found, the better it is possible to establish phenotype-genotype correlations. We report on a novel RET mutation at codon 611 in a family with MTC without other clinical manifestations and of rather benign course. Am.
