Nationwide study of patients with head and neck paragangliomas carrying <i>SDHB</i> germline mutations

Abstract

If an SDHB germline mutation is identified in a patient with HNPGL, the clinician should be aware of the variable manifestations of the SDHB-linked tumour syndrome, the risk of catecholamine excess, concurrent phaeochromocytoma, and association with non-paraganglionic tumours.
