Multiple endocrine neoplasia type2A (MEN 2A) is a syndrome of familial cancers characterized by medullary thyroid carcinoma (MTC), pheochromocytoma and hyperplasia of the parathyroid glands. RET protooncogene is the responsible gene for MEN 2A; in more than 96% of MEN 2A families mutations in RET exon 10 or exon 11 are identified. Herein we report a MEN 2A case affected by a mutation (Gly533Cys) in exon 8. A 66-yr-old male patient was referred to our Department due ...

Medullary Thyroid Carcinoma (MTC) is a rare cancer that arises from the thyroid C-cells and occurs as sporadic in 75% of the cases. In 25% of MTC cases, mutations of the RET proto-oncogene are responsible for the development of three dominantly inherited neoplastic disorders including multiple endocrine neoplasia (MEN) 2A, MEN 2B and familial medullary thyroid carcinoma (FMTC). Since 2–8% of MTC cases considered sporadic conceal germline mutations, direct analysis of the ...
