What is the most common manifestation of a MEN1?
Multiple parathyroid tumors causing primary hyperparathyroidism are the most common manifestation of MEN1, with over 90 percent penetrance by age 50 to 70 years [ 1-3 ]. Pathologic hypercellularity of multiple glands is common in these patients and, given sufficient time, perhaps universal. Patients with classical MEN1 are at high risk of recurrent hyperparathyroidism after apparently successful subtotal parathyroidectomy.
What is a MEN1?
Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant disorder classically characterized by predisposition to tumors of the parathyroid glands (which occur in the large majority of patients by age 50 years), anterior pituitary, and pancreatic islet cells ( table 1 ). MEN1 also includes a predisposition to gastrinomas in the duodenum, carcinoids, adrenal adenomas, angiofibromas, lipomas, and other tumors ( table 2 ). The most common types of tumors in MEN1 are generally benign, but malignancy of some carcinoid, islet cell, and gastrointestinal tract tumors are important causes of mortality in MEN1. Treatment of MEN1 can differ markedly from that of more common sporadic forms of the relevant endocrine tumors, and referral to centers with major experience and multidisciplinary expertise in MEN1 is strongly recommended.
What is MEN1 tumor?
MEN1 causes tumors to develop in endocrine glands and other parts of the body. Although most of these tumors are noncancerous, they can cause the affected glands to increase in size and become overactive, producing too much hormone.
What are the most common pituitary tumors?
In people with MEN1, the two most common pituitary tumors are. Prolactinomas. The most common pituitary tumor in people with MEN1, prolactinomas produce the hormone prolactin. Normally, this hormone signals women’s breasts to produce milk during pregnancy and breastfeeding.
What is a MEN1?
Multiple endocrine neoplasia type 1 (MEN1) is a rare genetic disorder that mainly affects the endocrine glands. Located in different parts of the body, these glands control the production of hormones that direct many body processes, including growth, digestion, and sexual function. MEN1 can affect the parathyroids, pancreas, and pituitary glands.
What is MEN1 in biology?

Where is the parathyroid gland located?
The parathyroid glands are located on or near the thyroid gland in the neck. Hyperparathyroidism. MEN1-related tumors cause the parathyroid glands to become overactive, producing too much parathyroid hormone. This condition, called hyperparathyroidism, is the most common complication associated with MEN1.
Where do tumors form?
Over time, some of these tumors may become cancerous. Insulinomas. These tumors form only in the pancreas, in cells that produce the hormone insulin. Insulin controls levels of blood glucose (blood sugar) by moving glucose into the cells, where it can be used for energy.
What are some examples of MEN1?
MEN1 can also cause tumors in other parts of the body. Examples include. tumors in other endocrine glands, such as the adrenal glands. carcinoid tumors —slow-growing tumors most often found in the stomach, thymus, and lungs.

What is multiple endocrine neoplasia?
Collapse Section. Multiple endocrine neoplasia is a group of disorders that affect the body's network of hormone-producing glands called the endocrine system. Hormones are chemical messengers that travel through the bloodstream and regulate the function of cells and tissues throughout the body.
What are the different types of endocrine neoplasia?
The major forms of multiple endocrine neoplasia are called type 1, type 2, and type 4. These types are distinguished by the genes involved, the types of hormones made, and the characteristic signs and symptoms. Many different types of tumors are associated with multiple endocrine neoplasia. Type 1 frequently involves tumors ...
Is endocrine neoplasia type 1 autosomal dominant?
Multiple endocrine neoplasia type 1 usually has an autosomal dominant pattern of inheritance. People with this condition are born with one mutated copy of the MEN1 gene in each cell. In most cases, the altered gene is inherited from an affected parent.
What is the name of the tumor that causes high blood pressure?
Some people with this disorder also develop a pheochromocytoma, which is an adrenal gland tumor that can cause dangerously high blood pressure. Multiple endocrine neoplasia type 2 is divided into three subtypes: type 2A, type 2B (formerly called type 3), and familial medullary thyroid carcinoma (FMTC).
What is the function of menin?
Although the exact function of menin is unknown, it is likely involved in cell functions such as copying and repairing DNA and regulating the activity of other genes. When mutations inactivate both copies of the MEN1 gene, menin is no longer available to control cell growth and division.
What happens if you have a MEN1 mutation?
Almost everyone who is born with one MEN1 mutation acquires a second mutation in certain cells, which can then divide in an unregulated way to form tumors. Multiple endocrine neoplasia type 2 and type 4 are also inherited in an autosomal dominant pattern.
What is the RET gene?
Mutations in the RET gene cause multiple endocrine neoplasia type 2. This gene provides instructions for producing a protein that is involved in signaling within cells. The RET protein triggers chemical reactions that instruct cells to respond to their environment, for example by dividing or maturing.
