#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.

#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.
