Suspicion for MEN1 is described as: parathyroid adenoma below the age of 30 years (or multiglandular parathyroid disease at any age); gastrinoma or multiple pancreatic NET at any age or individuals who have two or more MEN1-associated tumors that are not part of the classical triad of parathyroid, pancreatic islet and anterior pituitary tumors (e.g., parathyroid tumor plus adrenal tumor) (10). This evidence concerns the gene MEN1 and parathyroid gland disorder.
