Clinically Guided Genetic Screening in a Large Cohort of Italian Patients with Pheochromocytomas and/or Functional or Nonfunctional Paragangliomas

TLDR
The frequency of the hereditary forms of pheochromocytoma/paraganglioma varies depending on the family history and the clinical presentation, and which genes should be screened first is suggested.
Abstract
Purpose: The aim of the study was to define the frequency of hereditary forms and the genotype/phenotype correlations in a large cohort of Italian patients with pheochromocytomas and/or functional or nonfunctional paragangliomas. Design: We examined 501 consecutive patients with pheochromocytomas and/or paragangliomas (secreting or nonsecreting). Complete medical and family histories, as well as the results of clinical, laboratory, and imaging studies, were recorded in a database. Patients were divided into different groups according to their family history, the presence of lesions outside adrenals/paraganglia considered syndromic for VHL disease, MEN2, and NF1, and the number and types of pheochromocytomas and/or paragangliomas. Germ-line mutations in known susceptibility genes were investigated by gene sequencing (VHL, RET, SDHB, SDHC, SDHD) or diagnosed according to phenotype (NF1). In 160 patients younger than 50 yr with a wild-type profile, multiplex ligation-dependent probe amplification assays were...

Pheochromocytoma and paraganglioma: An endocrine society clinical practice guideline

TL;DR: This evidence-based guideline recommends minimally invasive adrenalectomy for most pheochromocytomas with open resection for most paragangliomas and suggests personalized management with evaluation and treatment by multidisciplinary teams with appropriate expertise to ensure favorable outcomes.

Genetics and clinical characteristics of hereditary pheochromocytomas and paragangliomas

TL;DR: A thorough summary of the genetics and clinical features of these tumors is given, both as part of the classical syndromes such as multiple endocrine neoplasia type 2 (MEN2), von Hippel-Lindau disease, neurofibromatosis type 1, and succinate dehydrogenase-related PCC-PGL and within syndrome associated with a smaller fraction of PCCs/PGLs, such as Carney triad.

Mutations in SDHD, a Mitochondrial Complex II Gene, in Hereditary Paraganglioma

TL;DR: Analysis of families carrying the PGL1 gene revealed germ line mutations in the SDHD gene, which indicates that mitochondria play an important role in the pathogenesis of certain tumors and that cybS plays a role in normal CB physiology.

Mutations in SDHC cause autosomal dominant paraganglioma, type 3.

TL;DR: Nonchromaffin paragangliomas are usually benign, neural-crest–derived, slow-growing tumours of parasympathetic ganglia that are transmitted as autosomal dominant traits with incomplete and age-dependent penetrance.
