Rare Endocrine Conditions

Using the classification of endocrine conditions, Endo-ERN established eight main thematic groups (MTGs). These MTGs are organ and/or physiology based, cover care throughout the entire lifespan of patients and the total spectrum of congenital and acquired conditions.

MTG1

Adrenal

Rare adrenal disorders comprise those with hormonal oversecretition and/or overgrowth and those with inappropriate low endocrine functionality. Oversecretion and tumour growth often requires surgical or targeted medical therapy, patients with adrenal insufficiency need hormonal replacement therapy.

MTG2

Disorders of Calcium & Phosphate Homeostasis

Calcium and Phosphate Homeostasis is of major importance to a large number of hysiological processes thereby affecting several organ systems typically bone, muscles, kidney, brain with consequences on quality of life and risk of chronic disability.

MTG3

Genetic disorders of Glucose & Homeostasis

For genetic disorders of glucose and insulin homeostasis 3 subthematic subgroups are defined: Insulin-resistance syndrome; Hyperinsulinism and other forms of hypoglycemia Rare diabetes mellitus.

MTG4

Genetic Endocrine Tumour Syndromes

Multi-organ conditions that are dominantly inherited, and manifest throughout childhood and adult life. In recent years predictive testing has been introduced, with patients being identified in the preclinical state, and often in early childhood.

MTG5

Growth & Genetic Obesity Syndromes

A group of imprinting disorders for which care have been well organised: Prader Willi Syndrome, Silver Russell Syndrome, and Beckwith Wiedemann Syndrome and a group of Growth hormone and IGF-I insensitivity including Laron and Noonan Syndrome, as well as other overgrowth and growth retardation syndromes.

MTG6

Hypothalamic and Pituitary Conditions

Rare pituitary disorders are a group of various clinical syndromes with low prevalence (main groups 100-500 million, specific diseases/genetic disorders less than 1 million) requiring multidisciplinary and lifelong care because of the central endocrine function of the pituitary.

MTG7

Sex Development & Maturation

This Main Thematic Group (MTG) is dedicated to the Disorders of sex development (DSD) and the Disorders of sex maturation (DSM). These are medical conditions involving the reproductive system in both sexes.

MTG8

Thyroid

There are 3 subthematic groups for Thyriod: a) Rare Thyroid Hormone Signaling Disorders (causing defect in thyroid hormone signaling and action), b) congenital hypothyroidism (a rare disorder for which all newborns in the EU are screened immediately after birth) and hyperthyroidism, and c) non-metastatic thyroid carcinoma.

Within MTGs. several sub-thematic groups have been defined on the basis of presence of hormonal overproduction, insufficiency, resistance and/or tumour growth.  

With these sub-thematic groups, Endo-ERN envisions addressing the specific condition’s unmet needs and highly specialised interventions required for patients with related conditions.
