Allelic loss from chromosome 11 in parathyroid tumors.
Parathyroid tumors may occur in a sporadic fashion or, more rarely, as part of a familial syndrome (such as familial multiple endocrine neoplasia type I). The MENI gene has been mapped by linkage analysis to chromosome 11 at band q11-q13, and presumably acts as a tumor suppressor gene. In the present study, which is an extension of our previous studies, we examined 41 parathyroid tumors from pa...
متن کامل11q13 allelic loss in pituitary tumors in patients with multiple endocrine neoplasia syndrome type 1.
Pituitary adenomas may develop sporadically or as part of the multiple endocrine neoplasia type 1 (MEN 1) syndrome. The gene responsible for MEN 1 syndrome was recently identified and cloned. Low rates of MEN 1 gene mutations and deletions have been reported in sporadic pituitary adenomas. To elucidate the role of the MEN 1 gene in the pathogenesis of MEN 1-associated pituitary tumors, we exami...
متن کاملAllelic loss on chromosome 11 in hereditary and sporadic tumors related to familial multiple endocrine neoplasia type 1.
Familial multiple endocrine neoplasia type 1 (FMEN1) is an autosomal dominant disorder characterized by tumors of the parathyroid glands, pancreatic islets, and anterior pituitary. The gene for this disease maps to chromosome 11q12-11q13, and allelic loss in this region has been shown in both sporadic and FMEN1-related parathyroid tumors. FMEN1-related pancreatic islet tumors, and rarely in spo...
متن کاملGastroenteropancreatic Neuroendocrine Tumors in Multiple Endocrine Neoplasia Type 1
We reviewed the literature about entero-pancreatic neuroendocrine tumors in Multiple Endocrine Neoplasia type 1 syndrome (MEN1) to clarify their demographic features, localization imaging, practice, and appropriate therapeutical strategies, analyzing the current approach to entero-pancreatic neuroendocrine tumors in MEN1. Despite the fact that hyperparathyroidism is usually the first manifestat...
متن کاملMultiple endocrine neoplasia type I.
An adult woman 43 years old, with Multiple Endocrine Neoplasia type 2A (MEN2A). Clinical diagnosis of MEN2A was made based on the chief complaints of abdominal pain and a lump in the front left side area of neck accompanied with weight loss, from laboratory examination revealed an increased level of plasma levels of calcitonin levels with the result of 6359 pg/ml and 24 hours metanephrine urine...
