Multiple endocrine neoplasia(MEN-1) is also known as Wermer's syndrome. MEN-1 is a hereditory disorder .This type of hereditory disosorder generally passed from one generation to next generation. It affects the hormone producing glands.This disorder increases the development of tumors like cancerous and non cancerous tumors in glands.Non cancerous tumors may develop in parathyroid glands,Neuroendocrine system,anterior pituitory glands and skin. The symptoms are tiredness, bone pain, fractures and kidney stones, as well as stomach or intestinal ulcers.
A MEN1 mutation was found in 15.9% of 365 patients. Recurrent primary hyperparathyroidism (pHPT; odds ratio (OR) 162.40); nonrecurrent pHPT (OR 25.78); pancreatic neuroendocrine tumors (pNETs) and duodenal NETs (OR 17.94); pituitary tumor (OR 4.71); NET of stomach, thymus, or bronchus (OR 25.84); positive family history of NET (OR 4.53); and age (OR 0.96) predicted MEN1. The c-statistic of the prediction model was 0.86 (95% confidence interval (95% CI) 0.81-0.90) in the derivation cohort and 0.77 (95% CI 0.66-0.88) in the validation cohort.
