Brief Summary
The primary objective of the PGL.EXPO-2 study is to test the hypothesis that exposure (occupational, environmental and/or domestic) to succinate dehydrogenase inhibitors (SDHi) could contribute to tumor emergence in subjects carrying a germline mutation in one of the SDHx genes.The primary endpoint will be the proportion of subjects (cases or controls) exposed to SDHi and the association with paraganglioma risk. In addition, a blood sample (10 ml on EDTA) will be proposed to the participants to the study

Study Arms (2)
Cases
Cases: SDHx mutation carriers diagnosed for a SDHx-related tumor
Controls
Controls : SDHx mutation carriers with no SDHx-related tumor
Eligibility Criteria
650 cases and 650 controls will be enrolled in different French referral centers where they are regularly managed and followed for a SDHx-related tumor risk. They will be matched on their date of birth
You may qualify if:
- Cases: SDHx mutation carriers diagnosed for a SDHx-related tumor
- Controls: SDHx mutation carriers with no SDHx-related tumor
You may not qualify if:
- Incapacity to exercise free and informed consent for the study
- Patient under tutorship or guardianship or legal safeguard

- Access Criteria
- Data sharing must be accepted by the sponsor and the PI based on a scientific project and scientific involvement of the PI team. Collaboration will be fostered. The founder could be involved in the decision. Teams wishing obtain IPD must meet the sponsor and IP team to present scientifics (and commercial) purpose, IPD needed, format of data transmission, and timeframe. Technical feasibility and financial support will be discussed before mandatory contractualization. Processing of shared data must comply with European General Data Protection Regulation (GDPR).
Individual participant data (IPD) that underlie results in publication could be shared. IPD detailed in the protocol of a planned metaanalysis could be shared
