Background
Multiple Endocrine Neoplasia type I: Wermer syndrome; MEN I
Multiple Endocrine Neoplasia type I is a rare genetic condition associated with tumours in the endocrine glands. The age of onset of MEN I is usually in the teenage years, although symptoms may not appear for several years. In most individuals, therefore, a diagnosis of MEN I is made by the fourth decade. MEN I affects men and women equally.
