Autosomal dominant hypophosphatemic rickets (ADHR) is a hereditary disorder characterized by isolate renal phosphate wasting, hypophosphatemia, and inappropriately normal 1,25(OH)2D3 levels. ADHR is caused by mutations in FGF23 protein that actively regulates phosphate homeostasis. In contrast to X-linked dominant hypophosphatemic rickets, ADHR shows incomplete penetrance, variable age at onset, and in rare cases resolution of the phosphate-wasting defect...
