Multiple endocrine neoplasia type 2A (MEN 2A) and familial medullary thyroid carcinoma (FMTC) are two closely related cancer syndromes inherited in an autosomal dominant manner. Mutations in the RET proto-oncogene were found in MEN 2A and FMTC families. In this study we report seven different germline mutations in the RET proto-oncogene in five of five MEN 2A and five of six FMTC families. Each of the mutations involves a cysteine residue in the extracellular cysteine-rich domain of the RET receptor tyrosine kinase. We developed simple polymerase chain reaction based diagnostic tests for all seven mutations in these families.
