The causative mutation is in the MEN1 gene at 11q13 which encodes a nuclear protein called menin that is believed to act as a tumor suppressor. Most cases of multiple endocrine neoplasia type 1 are inherited in an [[autosomal dominant]] pattern.

{{main|Multiple endocrine neoplasia type 2}}
MEN syndrome types 2 and 3 have their basis in molecular genetics. Individuals can be tested for this genetic disorder reliably even when asymptomatic. The mutation is in the [[RET proto-oncogene]]. Most cases of multiple endocrine neoplasia types 2 and 3 are inherited in an [[autosomal dominant]] pattern.
Type 2 is also known as Sipple syndrome (after the American Dr John H. Sipple, who described it in 1961)<ref>Sipple JH. ''The association of pheochromocytoma with carcinoma of the thyroid gland.'' Am J Med 1961;31:163-166.</ref> and used to be called type 2A:
#[[Medullary carcinoma]] of the [[thyroid]] which is associated with increased [[calcitonin]] secretion. A test for elevated calcitonin should be done after [[pentagastrin]] injection and/or calcium infusion, to ensure that all affected patients are detected.
#[[Pheochromocytoma]]
#[[Parathyroid]] hyperplasia/tumour causing [[hyperparathyroidism]].
===MEN type 3/type 2b===
This syndrome has no eponym; it was described by Schimke ''et al'' in 1968.<ref>Schimke RN, Hartmann WH, Prout TE, Rimoin DL. ''Syndrome of bilateral pheochromocytoma, medullary thyroid carcinoma and multiple neuromas. A possible regulatory defect in the differentiation of chromaffin tissue.'' [[N Engl J Med]] 1968;279:1-7.

Overview

Historical Perspective

Classification

MEN type 1

Type 1 is also known as Wermer's syndrome after Dr Paul Wermer, who described it in 1954:[3]

  1. Parathyroid hyperplasia/tumour causing hyperparathyroidism.
  2. Pancreatic islet cell tumours causing hypoglycaemia (insulinoma) and Zollinger-Ellison syndrome (gastrinoma).
  3. Pituitary adenoma which may cause pituitary hormone excess.

The causative mutation is in the MEN1 gene at 11q13 which encodes a nuclear protein called menin that is believed to act as a tumor suppressor. Most cases of multiple endocrine neoplasia type 1 are inherited in an autosomal dominant pattern.

MEN type 2

MEN type 2/type 2a

MEN syndrome types 2 and 3 have their basis in molecular genetics. Individuals can be tested for this genetic disorder reliably even when asymptomatic. The mutation is in the RET proto-oncogene. Most cases of multiple endocrine neoplasia types 2 and 3 are inherited in an autosomal dominant pattern.

Type 2 is also known as Sipple syndrome (after the American Dr John H. Sipple, who described it in 1961)[4] and used to be called type 2A:

  1. Medullary carcinoma of the thyroid which is associated with increased calcitonin secretion. A test for elevated calcitonin should be done after pentagastrin injection and/or calcium infusion, to ensure that all affected patients are detected.
  2. Pheochromocytoma
  3. Parathyroid hyperplasia/tumour causing hyperparathyroidism.

MEN type 3/type 2b

This syndrome has no eponym; it was described by Schimke et al in 1968.[5] Originally thought to be a third MEN, then considered a variant of II (especially after linkage to RET was confirmed), it is now considered its own syndrome.

  1. Pheochromocytoma
  2. Medullary carcinoma of thyroid which is associated with increased calcitonin secretion. A test for elevated calcitonin should be done after pentagastrin injection and/or calcium infusion, to ensure that all affected patients are detected.
  3. Mucosal neuromas which are usually situated in the gastrointestinal tract.

*- of patients with MEN1 and gastrinoma

FMTC = familial medullary thyroid cancer

  • Multiple endocrine neoplasia type 2b|MEN 2B is sometimes known as MEN 3 and the designation varies by institution (c.f. www.ClinicalReview.com).
  • Although a variety of additional eponyms have been proposed for MEN2B (e.g. Williams-Pollock syndrome, Gorlin-Vickers syndrome, and Wagenmann–Froboese syndrome), none ever gained sufficient traction to merit continued use and, indeed, are all but abandoned in the medical literature. Another early report was Schimke et al. in 1968.[15]
  • OMIM also includes a fourth form of multiple endocrine neoplasia ("MEN4"), associated with CDKN1B.[16] The presentation is believed to overlap that of MEN1 and MEN2.[17]
