Genetic Testing and SDHx Mutations:
What do they have to do with PGL/GIST/Pheos?

This webcast will highlight how SDHx mutations impact risks for paraganglioma, pheochromocytomas, and GIST. We’ll discuss why genetic testing is helpful for any diagnosis of GIST, paraganglioma or pheochromocytoma, and what the SDHx genes have to do with tumor risk. We’ll discuss what types of tumors are associated with mutations in the SDHx genes, and how different SDHx genes (SDHA, SDHB, SDHC, SDHD, SDHAF2) have different tumor and location risks. This webcast will highlight recommendations for screening and current research initiatives for SDHx and paragangliomas.
