#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.

#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.

#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.

#1057 Localisation of Insulinoma and Beta-Cells: Comparison of Glucagon-Like Peptide-1 Receptor (GLP1-R) SPECT/CT, PET/CT and MRI. Preliminary Results of a Prospective Clinical Study.
Introduction: SPECT/CT imaging with GLP1-R specific radiotracers like 111In-DOTA-exendin-4 have already proved to be a useful tool for the preoperative localisation of insulinomas. PET/CT has several advantages over SPECT/CT: lower radiation exposure, less time consumption and higher spatial resolution.

#477 Glucagon-Like Peptide 1 Receptor (GLP-1R) Imaging for the Preoperative Localization of Benign Insulinomas in 30 Patients
Introduction: Biochemical diagnosis of endogenous hyperinsulinemic hypoglycemia is straightforward. Surgical removal of an insulinoma is hampered by difficulties to localize it using conventional radiological procedures. In vitro data suggest that human insulinoma cells exhibit a high density of GLP-1R. 111In-exendin-4 is an 111In labeled GLP-1R agonist that binds with high affinity to GLP-1R and may be helpful in localizing insulinomas.

#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.

#2003 Comparison of Glucagon-Like-Peptide-1 (GLP-1) Receptor PET/CT, SPECT/CT and 3T MRI for the Localisation of Insulinomas: Evaluation of Accuracy in a Prospective Crossover Imaging Study
Introduction: Benign insulinomas are the most prevalent cause of endogenous hyperinsulinaemic hypoglycaemia (EHH) in adults and due to their small size difficult to localise.

#2271 Effects of Multi-Receptor Targeting Drugs in Neuroendocrine Tumors Using 3D Cell Culture
Introduction: Symptom control in functioning neuroendocrine tumors(NETs) may be difficult in some cases, thus, new therapeutic options, including multi-receptor targeting drugs are required.

#245 Expression of Somatostatin Receptors and Dopamine 2 Receptor in Lung Carcinoids as a Possible Biotherapy Target
Introduction: Expression of somatostatin receptors (SSTRs) and dopamine 2 receptor (D2R) in neuroendocrine tumors is of clinical importance, as somatostatin analogues and dopamine agonists are used in biotherapy.

#1063 Hypoglycaemia in a Patient with Glucagonoma-Coincidence of a Glucagonoma and Insulinoma in a Patient with Multiple Endocrine Neoplasia Type I
Introduction: We report the case of a 54 year old female with a known MEN1 syndrome with primary Hyperparathyroidism, a Prolactinoma and a pancreatic tumor. The patient complains about episodes of fatigue and sweating, both symptoms improve immediately after a meal.
