A Novel Missense Mutation of the TMEM127 Gene that Leads to Pheochromocytoma Phenotype Abstract #271

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.
Aim(s): To seek germline TMEM127 mutations in archival DNA of 5 PHEO patients without mutations in other susceptibility genes.
Materials and methods: The coding regions and the exon-intron junctions of the four exons of TMEM127 gene were amplified by PCR and directly sequenced.

#99 Gene mutations and Hypoxia Inducible Factor (HIF-1) expression as prognostic-predictive factors in pheochromocytomas/paragangliomas (P/P)
Introduction: P/P are rare tumors sporadically associated with familial disorders. In advanced/unresectable disease, no standard treatment has so far been well established. Recently a mutation of some genes (SDHB, SDHC, SDHD) involved in the pathogenesis of familial P/P was discovered. These mutations are often associated with an over-expression of HIF-1, which plays a central role in angiogenesis and cell proliferation. This pathway is known to be inhibited by some targeted therapies, such as sunitinib or sorafenib.

#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.

#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.

#861 Targeted Next Generation Sequencing in the Screening for Familial Neuroendocrine Tumor Syndromes: A Tool for Personalized Medicine
Introduction: Multiple syndromes are described as conferring susceptibility to NETs; MEN1 & 2, NF1, familial PGL 1-5, TSC, VHL and germline mutations in the HIF2A, MAX, or TMEM127. Genetic testing covering these diagnoses may be extensively resource-demanding using traditional techniques due to the large extent of these loci.

#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.
