P057: Incidence and phenotypic spectrum of SDHA pathogenic variants identified in an unselected precision medicine cohort*
Abstract
Germline pathogenic or likely pathogenic variants (P/LP) in SDHA are associated with Hereditary Pheochromocytoma and Paraganglioma syndrome (HPPS), which confers an increased risk for pheochromocytomas, paragangliomas, and gastrointestinal stromal tumors (GIST). Existing literature suggests that risk for these tumors is lower in SDHA-associated HPPS compared to other SDH complex genes. Increasing numbers of incidental SDHA P/LP variants are being identified with multigene panel testing (MGPT). These incidental variants are challenging to manage in the absence of personal or family history of associated tumors.
