Abstract

The syndrome of multiple endocrine neoplasia type 1 is an autosomal dominantly inherited disease affecting several endocrine organs. The affected organs include the pituitary, the parathyroids and endocrine pancreas, where different types of lesions can be found, such as hyperplasia or frank carcinomas. The most life threatening lesions are the endocrine pancreatic tumors, which cause about 80% of all deaths among the MEN-1 members. In our own series of 108 members from 16 families with multiple endocrine neoplasia, 55 members had the MEN-1 trait. Among these members, pituitary lesions were found in 42%, parathyroid involvement in 89% and endocrine pancreatic tumors in 58%. Hyperparathyroidism was the presenting lesion of the MEN-1 trait. By using a specific meal stimulation test we have been able to unveil pancreatic lesions up to a median of five years previous to radiological detection. Very recently we have been able to detect a specific genetic lesion in MEN-1 members by studying DNA rearrangements with recombinant DNA technique, using the method of polymorphic restriction enzyme recognition in three large kindreds. The MEN-1 locus maps to chromosome 11q and the MEN-1 predisposition would be a constitutional mutation in he...Continue Reading

This feed focuses on a rare genetic condition called Autoimmune Polyendocrine Syndromes, which are characterized by autoantibodies against multiple endocrine organs. This can lead to Type I Diabetes.

Carcinoma, Islet Cell

Islet Cell Carcinoma or Pancreatic Neuroendocrine Tumours arises in the hormone producing cells of the pancreas. These tumors can be either malignant or benign. Discover the latest research on Islet Cell Carcinoma here.
