Background: X-linked hypophosphatemia (XLH) is a rachitic disorder characterized by renal tubular phosphate wasting resulting from increased circulating activity of the fibroblast growth factor FGF23. Secondary and tertiary hyperparathyroidism have been reported in XLH patients in small retrospective studies, however this complication has never been systematically evaluated in a large cohort.Aim of the study: To compare parathyroid function of adult XLH ...

Context: Primary bilateral macronodular adrenal hyperplasia (PBMAH) with glucose-dependent insulinotropic polypeptide (GIP)-dependent Cushing’s syndrome is caused by ectopic expression of GIP receptor in the adrenal tissue. The bilateral nature of this adrenal disease suggests germline genetic predisposition. We aimed to identify the molecular driver event responsible for ectopic GIP receptor expression in PBMAH.Methods: We conducted an internationa...
