#1256 Characterization and Rescue of a Pathogenic D63N Mutant Human Glucagon Receptor That Causes a Pancreatic Neuroendocrine Tumor Syndrome (Mahvash disease)

Introduction: We have previously demonstrated that inactivating glucagon receptor (GCGR) mutations cause a novel hereditary human disease of hyperglucagonemia, pancreatic α cell hyperplasia, and pancreatic neuroendocrine tumor (Mahvash disease). We recently identified a novel missense GCGR mutation, D63N, in a family with Mahvash disease.

#1253 A Novel Hereditary Pancreatic Neuroendocrine Tumor Syndrome Associated with Biallelic Inactivation of the Glucagon Receptor

Introduction: Hereditary pancreatic neuroendocrine tumors (PanNETs) are associated with 4 known autosomal dominant syndromes including MEN1, vHL disease, NF1, and TS. Glucagon receptor (GCGR) inactivation in human (Mahvash disease) has been associated with asymptomatic hyperglucagonemia, α-cell hyperplasia, and PanNET, and may represent a new hereditary syndrome.

#691 Pancreatic Focal Alpha Cell Hyperplasia with Hyperglucagonaemia without the Glucagonoma Syndrome

Introduction: Pancreatic alpha cell hyperplasia and hyperglucagonaemia without the glucagonoma syndrome is a rare clinical syndrome not widely recognised. Here we describe a novel mutation in the glucagon receptor gene (GCGR) in a patient with the disease.

#564 Genetic Alterations in Glucagon Cell Adenomatosis

Introduction: Glucagon cell adenomatosis (GCA) was recently recognized by us as a multifocal neoplastic disease of the endocrine pancreas unrelated to MEN-1. Multiple micro- and a few macrotumors are found on the background of a hyperplasia of glucagon cells. The disease may cause unspecific abdominal symptoms and only rarely a glucagonoma syndrome. Recently a mutation in the glucagon receptor (GCGR) gene was described in one GCA patient.
