PTH and X-linked dominant hypophosphatemic rickets: Laboratory tests of all subjects revealed typical features of XLHR: normal levels of calcium (9.5±0.5 mg/dL; range 8.5–10.3 mg/dL), low levels of serum phosphate (2.7±0.5 mg/dL; range, 2.0–3.6 mg/dL), TRP (69.8±8.0%, range, 59.9–79.6%), and TmP/GFR (1.88±0.36; range, 1.31–2.48), increased levels of ALP (598±175 IU/L; range, 364–925), and normal/mildly increased levels of PTH (84.5±34.8 pg/mL; range, 31.9–154.7).
