Identifying Novel Mechanisms for Dentoalveolar Mineralization Defects in X-linked Hypophosphatemia
PROJECT SUMMARY/ABSTRACT Mutations in the PHEX gene cause X-linked hypophosphatemia (XLH), the most common form of hereditary rickets. In XLH, elevated fibroblast growth factor 23 (FGF23) causes renal phosphate (Pi) wasting, hypophosphatemia, reduced 1,25-dihydroxyvitamin D (1,25D), and secondary hyperparathyroidism, all contributing to mineralization disturbances in the skeleton and dentition. Yet current treatments lack efficacy and no treatments are available to specifically improve associated dentoalveolar defects that substantially affect oral health and quality of life in individuals with XLH. Limited efficacy of treatments to date is in part related to the complex etiology of…
