Genetic Alterations in Glucagon Cell Adenomatosis Abstract #564

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.
Aim(s): To investigate GCGR gene changes in five patients with GCA.
Materials and methods: Paraffin-embedded and formalin-fixed pancreatic tissues from five patients with GCA were macro- or microdissected. The extracted DNA was sequenced and the GCGR gene analysed for mutations.

#562 Expression of Chromosome 18 Related Tumor Suppressor Proteins in Ileal Neuroendocrine Tumors
Introduction: The genetic alterations in ileal neuroendocrine tumors (iNETs) are poorly
characterized. The most frequent chromosomal aberration is the loss of one
chromosome 18 in iNETs, however, the relevance of this alteration is unclear.
