#1461 Whole Exome Sequencing of Three Families with Small Intestine Neuroendocrine Tumors
Introduction: Small intestine neuroendocrine tumors (siNETs) are the most prevalent small intestine neoplasms. However, familial siNETs are rarely described.

#2283 Ultra-Deep Targeted Resequencing Reveals Recurrent DAXX and CYFIP2 Mutations and Implicates Novel Pathways in Pancreatic Neuroendocrine Tumors
Introduction: Recent studies in pancreatic neuroendocrine tumors have identified mutations in DAXX/ATRX, MEN1, and genes involved in the phosphoinositide-3-kinase/Akt/mammalian target of rapamycin (PI3K-Akt-mTOR) pathway. However, these studies focused on abundant mutations.

#122 Molecular genetic findings in gastric carcinoid suggest possible neurofibromin/Ras pathway involvement in carcinoid pathogenesis
Introduction: The molecular pathogenesis of gastrointestinal carcinoid tumours is poorly understood. We have been undertaking molecular genetic investigations of a young woman with neurofibromatosis type 1 (NF1) in whom a gastric carcinoid tumor was detected following an episode of gastrointestinal bleeding. She was otherwise relatively mildly affected by NF1. In NF1, gastric carcinoids have been found previously only in patients with other predisposing factors, which were absent in this patient.

#360 High Resolution (Epi)genomic Analysis Comparing Pulmonary Carcinoids with a Favorable and a Poor Disease Outcome
Introduction: Lung carcinoids are a heterogenous group of neuroendocrine tumors. MEN1 mutations and 11q22-q25 deletions have been implied in their tumorigenesis. Very few genome wide and methylation studies have been conducted to further elucidate molecular mechanisms underlying tumorigenesis.

#167 Localization of Sporadic Neuroendocrine Tumors by Gene expression Analysis of Their Metastases
Introduction: Primary neuroendocrine tumors (NETs) are rare and often difficult to detect, leading to diagnosis late in their development. Cases in which the primary cannot be located are denoted as CUP-Syndrome.

#462 Genome-Wide Expression Profiling Reveals Downregulation of OTP and CD44 and Upregulation of RET as Indicators of Poor Prognosis in Lung Carcinoids
Introduction: Lung carcinoids comprise a heterogeneous group of neuroendocrine tumors. Only few parameters have been identified that correlated with poor disease outcome, including 11q22-q25 deletions. New biomarkers are required to further improve diagnosis and prediction of prognosis.

#62 Genome-wide DNA methylation profiling of pancreatic neuroendocrine tumors identifies distinct methylation profiles and differentially methylated gene promoter regions associated with low, medium and high grade tumors
Introduction: Integration of genetics and epigenetics has emerged as a powerful approach to studying cellular differentiation (Mikkelsen et al, 2009) and tumorigenesis (Shen et al, 2007). The study of DNA methylation is of particular importance in cancer, as causal involvement has been demonstrated and it is the most stable of all epigenetic modifications, making it a desirable marker for both early detection and treatment of tumors. Hypermethylation of CpG sites in gene promoter regions leads to decreased gene expression; if such a gene is a tumor suppressor, this leads to carcinogenesis. To date, there have been no studies of genome-wide DNA methylation profiling of NETs. This study sets out to determine the DNA methylation profiles of low, intermediate and high grade pancreatic NET liver metastases with the intention of identifying dysregulated biological pathways in the development of these tumors. A protocol for the analysis formalin-fixed paraffin embedded tissue (FFPE) has also been developed in order to study these tumors in significant numbers following this pilot study.

#89 Hyperplasia-adenoma sequence in pituitary carcinogenesis: new insight into the role of AIP gene
Introduction: Pituitary adenoma predisposition has been recently associated with germline mutations in the Aryl-Hydrocarbon Receptor Interacting Protein (AIP) gene. This association has been detected in familial and, more rarely, in sporadic cases. The mechanisms by which the AIP mutations promote pituitary adenoma development remain unknown.
