Laboratory analyses revealed hypophosphatemia with serum phosphate levels ranging from 0.25 to 0.64 mmol/L (normal range, 0.85- 1.51 mmol/L), elevated ALP levels ranging from 173 to 257 U/L (normal range, 30- 120 U/L), and increased PTH at 104.8 pg/mL (normal range, 15- 65 pg/mL). The gene discussed is PTH; the disease is hypophosphatemia.
