Genetic Testing Referral Rates for Pheochromocytoma and Paraganglioma in an Academic Tertiary Centre

Clinical Endocrinology, Volume 103, Issue 2, Page 147-156, August 2025.
ABSTRACT Background Clinical guidelines recommend genetic counselling for all patients with pheochromocytoma or paraganglioma (PPGL). Barriers to accessing genetics evaluation are incompletely understood. The objective of this study was to identify individual‐ and provider‐level barriers to genetic testing.
