Multiple Endocrine Neoplasia type I (MEN1) or Wermer syndrome is an autosomal dominant disease that predisposes patients to the development of endocrine tumours, principally parathyroid, pituitary or duodenal-pancreatic tumours. It is due to mutations that abolish the function of the MEN1 gene, which contributes to tumour regulation. It is a rare disease, with an estimated prevalence in the general population of 1/30,000. Penetrance of the disease is late but very high (almost 100% at 50 years of age). The first clinical manifestations usually appear after the age of 30 or 40 years.
The three cardinal endocrine characteristics of MEN1 are secreting tumours of the parathyroid, the pituitary gland and the pancreas. Tumours of the adrenal glands, bronchial or thymic endocrine tumours, ependymoma and meningioma of the central nervous system, visceral leiomyomas, and certain cutaneous tumours can also be found as well as these cardinal tumours.
The diagnosis of MEN1 is essential to ensure 1) appropriate therapeutic management of the proven endocrine manifestations 2) screening for other endocrine and non-endocrine tumours (lesions), 3) family screening of affected relatives whether they are symptomatic or not 4) the surveillance of thus diagnosed patients. Studies on mortality in MEN1 have shown that the causes of death are mainly due to the disease. The non-diagnosis of MEN1 is a cause of therapeutic failure in the management of the endocrine lesions. For the success of the surgical treatment of an isolated endocrine lesion it is important for patients to be oriented towards a diagnosis of MEN1 as the management is different from that in usual situations. Detection is thus of major importance, as early diagnosis can improve the management.
Even though the syndrome was discovered in 1903 by Erdheim and correctly documented in 1954 by Wermer, it was only in the 1970s that we became aware of the variety of clinical forms and attempted to codify its treatment. Nonetheless, published studies are fragmented and concern selected populations of few patients. They only partially answer questions arising in clinical practice concerning the prognosis and optimal management of patients. The natural history of the disease in all of its clinical forms is still poorly understood. Although advances in genetics have helped in the diagnosis of MEN1, some clinical forms are still difficult to associate with the syndrome: atypical forms, forms with hardly any symptoms and no genetic diagnosis (10%). These clinical forms need to be clarified to ensure optimal care. Only a large cohort will make it possible to describe the different forms of this disease and to clarify its prognosis
18 studies on the registry are indexed under Multiple Endocrine Neoplasia; 5 are open to participants now.
This study's planned enrollment of 2,000 is above the median of 629 across 11 observational studies indexed under Multiple Endocrine Neoplasia.

Counted across the registry records on this site, refreshed daily.
This cohort includes symptomatic individuals, whose diagnosis of NEM1 has been confirmed, and domiciled in France
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Patients with the following characteristics will also be included in the cohort:
asymptomatic patients who carry a characteristic mutation of MEN1. Current knowledge suggests that these patients will develop symptoms during their follow-up.
Exclusion Criteria:
patients who present a single-organ genetic endocrine disease associated with another genetic syndrome (familial isolated pituitary adenoma FIPA, familial isolated hyperparathyroidism FIHP)
patients will be regularly asked about their state of health (occurrence of a major health event that required hospitalization, for example ...), and about their living conditions (alcohol and tobacco consumption, socio-economic environment). Questionnaires of quality of life and satisfaction related to care will also be offered at regular intervals to better know the impact of their disease on their daily lives and their perception of their care.
