classified into three subtypes: MEN 2A, FMTC (familial medullary thyroid carcinoma) and MEN 2B. All three subtypes have a high risk for development of medullary carcinoma of the thyroid (MTC) ... The diagnosis of all three of the MEN 2 subtypes relies upon a combination of clinical findings, family history and molecular genetic testing of the RET gene (chromosomal locus 10q11) ... Familial medullary thyroid carcinoma (FMTC) is diagnosed in families with four cases of MTC in the absence of pheochromocytoma or parathyroid adenoma/hyperplasia [Eng et al 1996] ... Approximately 85% of families with FMTC have an identifiable RET mutation [Mulligan et al 1994, Mulligan et al 1995]. These mutations occur at one of the five cysteine residues (codons 609, 611, 618, 620, and 634) with mutations of codons 618, 620, and 634 each accounting for 25 to 35% of mutations ... Mutations involving the cysteine codons 609, 618, and 620 are associated with MEN 2A, FMTC, and HSCR1. Mutations in these codons are detected in about 10% of families with MEN 2A and 2/3 of families with FMTC ...
A Nationwide Clinical Survey of Patients with Multiple Endocrine Neoplasia Type 2 and Familial Medullary Thyroid Carcinoma in Japan
Masatoshi Iihara, et al; Japanese Journal of Clinical Oncology 1997
[for Professionals mainly]
MEN (multiple endocrine neoplasia) type 2 syndrome is an inherited disease characterized by medullary thyroid carcinoma, pheochromocytoma, hyperparathyroidism and/or developmental anomalies. Germ-line mutations of the RET proto-oncogene have recently been identified as the underlying cause of the syndrome. Accordingly, several investigators have advocated prophylactic total thyroidectomy for medullary thyroid carcinoma at an early age in MEN 2 gene carriers identified by DNA analysis ... obtaining data for 230 patients diagnosed as having MEN 2 ... 84 males and 146 females, with a median age of 37.5 years (range 5-83). Patients were categorized as 179 with MEN 2A, 17 with MEN 2B, 12 with familial medullary thyroid carcinoma and 22 'other'. Medullary thyroid carcinoma, pheochromocytoma and parathyroid lesions occurred in 224 (97%) ...

An inherited disorder that affects the endocrine glands. It is sometimes called familial multiple endocrine adenomatosis or Wermer's syndrome ...

The pituitary gland becomes overactive in about one of four persons with FMEN1 ...
