pancreatic endocrine tumors
Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant disorder characterized by the combined occurrence of parathyroid, pancreatic endocrine, and anterior pituitary tumors. MEN1 has two characteristics ; a hormone excess and a sometimes lethal outcome due to malignant tumors. The recent identification of the MEN1 gene has opened the door to a much deeper understanding of this syndrome. Germline MEN1 mutations have been identified in most MEN1 families. They were not found, however, in families with familial pituitary tumors. Thus, studies with the MEN1 gene helped to establish that mutation of some other gene(s) is likely causative of the MEN1 phenocopy. These recent advances provide for the identification of mutant MEN1 gene carriers who are at a high risk of developing MEN1. The protein encoded by the MEN1 gene has been shown to function in the regulation of JunD-activated transcription but much still remains to be elucidated.
