To read the full abstract: N Engl J Med 2018;378:1987-1998FGF-23 is the primary regulator of phosphate homeostasis and acts by inhibiting phosphate reabsorption in the kidney (1). Loss-of-function mutations in the gene encoding phosphate-regulating endopeptidase homolog X-linked (PHEX) results in excess circulating FGF-23, which impairs renal phosphate reabsorption causing hypophosphatemia...
