Genetic Analysis of Pheochromocytomas, Paragangliomas and Associated Conditions

Study Purpose

Pheochromocytomas and paragangliomas are neural crest-derived tumors of the nervous system that are often inherited and genetically heterogeneous. Genetic screening is recommended for patients and their relatives, and can guide clinical decisions. However, a mutation is not found in all cases. The aims of this proposal are to: 1) to map gene(s) involved in pheochromocytoma, and 2) identify genotype-phenotype correlations in patients with pheochromocytoma/paraganglioma of various genetic origins.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	Yes
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational [Patient Registry]
Eligible Ages	N/A and Over
Gender	All

- family member with diagnosis of pheochromocytoma and or paraganglioma.

- diagnosis of a pheochromocytoma- and or paraganglioma-associated condition.

- family member with diagnosis of a pheochromocytoma- and or paraganglioma-associated condition.

Exclusion Criteria:

- unconfirmed diagnosis of pheochromocytoma and/or paraganglioma or associated condition

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT03160274
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Pheochromocytoma and paragangliomas are tumors originated from neuroectoderm cells located in the adrenal or extra-adrenal paraganglia, often leading to increased secretion of hormones known as catecholamines. These tumors represent a potentially curable cause of hypertension and are malignant in about 10-15% of the cases. Approximately 40% of patients with pheochromocytomas and/or paraganglioma have an inherited mutation. In addition, some patients and/or their relatives that are mutation carriers can develop other tumors as part of inherited cancer susceptibility syndromes. Therefore, detection of the susceptibility mutation is important for diagnosis and follow up. However, the susceptibility gene mutation cannot be identified in all cases. Studies that aim to identify novel susceptibility genes for pheochromocytoma are required. The fist aim of this study is to identify novel pheochromocytoma susceptibility genes. Characterization of such gene(s) can improve our understanding of the pathogenesis pheochromocytoma and paraganglioma and have an impact in diagnosis, therapeutic planning and genetic screening of relatives. The second aim of this project is to characterize relationships between mutations and clinical features that can provide insights into clinical surveillance and screening of at-risk individuals.
