NCIt definition : An autosomal dominant renal phosphate wasting disorder that results in rickets.;
Alternative definition : NICHD: Hypophosphatemic rickets due to heterozygous mutation(s) in the FGF23 gene,
encoding fibroblast growth factor 23, a protein involved in phosphate homeostasis.
The altered protein is resistant to cleavage, resulting in elevated FGF23 concentrations;
the condition is characterized by isolated renal phosphate wasting, resulting in hypophosphatemia,
accompanied by inappropriately normal 1,25-dihydroxyvitamin D (calcitriol) concentrations.;
