#4353 Familial inactivating glucagon receptor mutation resulting in pancreatic neuroendocrine tumours with metastatic potential, somatic MEN1 mutations, and a heterozygous phenotype

Introduction: Homozygous pathogenic glucagon receptor (GCGR) mutations cause a syndrome with pancreatic glucagon cell hyperplasia and neoplasia (GCHN) associated with Mahvash disease. This is an exceptionally rare autosomal recessive hereditary pancreatic neuroendocrine tumour (panNET) syndrome, with approximately ten cases documented in the literature.
