#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.

#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.

#1160 Exclusive Hotspot Mutation of YY1 Gene in Insulinomas and Extensive Mutation of DAXX in PNETs
Introduction: Somatic mutation of YY1 was shown in sporadic insulinoma, the main type of functional PNET. DAXX mutation occurred mainly in NF-PNET. However, YY1 and DAXX mutations in non-insulinomas and insulinomas, respectively, have not been well elucidated.

#2982 Comprehensive Molecular Analysis Identifies Driver Mutations in Metastases of Sporadic Well-Differentiated Neuroendocrine Tumours of the Small Intestine
Introduction: Small intestinal neuroendocrine tumours (SI-NETs) represent a heterogenous group of tumours. The molecular mechanisms which contribute to progression of SI-NETs are poorly elucidated. They are considered to be molecularly distinct from neuroendocrine carcinomas (NECs), which share oncogenic pathways with adenocarcinomas.

#1892 Feasibility and Implication of Routine NGS Analysis in Neuroendocrine Carcinomas
Introduction: Neuroendocrine carcinomas (NECs) may arise from any organ system, exhibit various degree of differentiation and have Ki67 indices ranging from 21-100%. After first-line platin based chemotherapy, no standard treatment exists.

#1059 Genomic Profiling of Metastatic Gastroenteropancreatic Neuroendocrine Tumor (GEP-NET) Patients in Precision-Medicine Era
Introduction: We have conducted molecular profiling through high-throughput molecular test as part of clinical practice for patients with advanced gastrointestinal (GI) cancer, or rare cancer including gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

#2215 Development of Multiplex Biomarker Assay to Subtype Pancreatic Neuroendocrine Tumors (PanNETs) with Distinct Prognosis and Mutations
Introduction: Overall 5-year survival for PanNETs ranges from 25-100%. The treatment paradigm for PanNETs largely based upon grades, which is significantly heterogeneous. We previously defined three molecular subtypes (distributed grades) of PanNETs using PanNETassigner signature. There is an unmet clinical need for prognostic and predictive biomarkers and clinically-relevant assays to complement grade and improve patient stratification.

#271 A Novel Missense Mutation of the TMEM127 Gene that Leads to Pheochromocytoma Phenotype
Introduction: Recently, truncating germline mutations in TMEM127 gene have been identified in 30% of familial cases of adrenal pheochromocytoma (PHEO) and in 3% of apparently sporadic cases.

#273 The Succinate Dehydrogenase Genetic Testing in Patients with Extra-adrenal Paragangliomas: The Portuguese Cancer Center (Lisboa) Experience
Introduction: Extra-adrenal paragangliomas (PGLs) occur as sporadic or familial entities, the latter mostly in association with germline mutations of the SDHB, SDHC or SDHD genes.

#2965 Molecular Signature of Rectal Neuroendocrine Neoplasia
Introduction: Rectal neuroendocrine tumors are rare neuroendocrine neoplasias (NEN). Little is known about prevalence and type of somatostatin receptor subtypes (sstr) expression and somatic mutations in relation to long-term clinical outcome.
