#2855 Whole Exome Sequencing Reveals the Monoclonal Origin of Gastric Mixed Adenoneuroendocrine Carcinomas
Introduction: Gastric mixed adenoneuroendocrine carcinomas (g-MANECs) are rare neoplasms consisting of adenocarcinoma and neuroendocrine neoplastic components. G-MANECs show more malignant characteristics than gastric adenocarcinomas, while molecular mechanisms underlying the co-existence of the two components remains unknown.

#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.

#2896 Comparative Genomic Analysis of High Grade Neuroendocrine Neoplasms across Diverse Organs
Introduction: Grade 3 neuroendocrine neoplasms (G3 NENs), if poorly differentiated, have a median survival of 10-19 months. Little is known regarding biologic differences between G3 NENs from different primary sites, most commonly GI and lung.

#2293 Genomic and Transcriptomic Characterization of Aggressive Well Differentiated Pancreatic Neuroendocrine Tumors (WD PanNET)
Introduction: While the genomic and transcriptomic landscape of low proliferating PanNET have been well studied, pathways driving aggressive WD PanNET are still unclear.

#658 Somatic Mutations in H-RAS in Sporadic Pheochromocytoma and Paraganglioma Identified by Exome Sequencing.
Introduction: Up to 60% of pheochromocytoma (PCC) and paraganglioma (PGL) are associated with mutations in established PCC and PGL susceptibility loci. A majority of unexplained cases are characterized by an increased activity of the RAS/RAF/ERK signalling pathway. Mutations in RAS subtypes H, K and N are common in human cancers, however, previous studies have been inconsistent regarding the mutational status of RAS in PCC and PGL.

#2781 Case Report: Whole Exon Sequencing of Primary Lesion and Metastatic Liver Lesion in Pancreatic Neuroendocrine Tumor
Introduction: Pancreatic neuroendocrine neoplasms(NENs) are classified into neuroendocrine tumors (NET) G1, G2, G3, and neuroendocrine carcinoma (NEC), which are different pathogenesis. The two kinds of tumors that occurs in the same lesion in one patient is very rare. We found high grade neuroendocrine neoplasms(NENG3) with a diameter of 0.1 cm in a patient with a pancreatic NETG2 (1.7 cm in diameter). The cells were significant atypia with Ki67 index of 60%, focal necrosis, while metastatic nodules in the liver (12, 0.1-1.1 cm in diameter) were all high grade NENG3.

#775 Whole Exome Sequence Of BON-1 And QGP-1, Two Human Pancreatic Neuroendocrine Tumor Cell Lines, Reveals Homozygous Loss Of Function Mutations In TP53, HRNR and CYFIP2.
Introduction: The human BON-1 and QGP-1 cell lines are two models often used in pancreatic neuroendocrine tumor (PNET) research. Data on protein-changing mutations in these cell lines is lacking.

#977 Inducing, Understanding and Overcoming Resistance to Everolimus in Pancreatic Neuroendocrine Tumors
Introduction: Treatment with the mTOR-inhibitor everolimus improves progression-free survival in advanced pancreatic neuroendocrine tumors (PNETs). However, adaptive resistance to mTOR inhibition is described.

#366 Next Generation Sequencing is a Cost Effective and Time Saving Method in Clinical Genetic Screening of Patients with Pheochromocytomas
Introduction: Pheochromocytomas are rare tumours arising from adrenal medulla. Recent findings show that about 30-40% of pheochromocytomas are caused by germline mutations in one of the ten hereto known susceptibility genes: SDHA, SDHB, SDHC, SDHD, SDHAF2, RET, VHL, NF1, TMEM127 and MAD. This list of genes is constantly growing. These ten genes together consist of 128 exons and a genetic screening test is both extensive time-consuming and expensive. We introduce utilizing Next generation sequencing as a fast and cost effective method.
