In 2018, mild hypercalcemia (2.63 mmol/l, NR 2.15-2.55 mmol/l), normophosphatemia (1.18 mmol/l, NR 0.81-1.45 mmol/l) with elevated parathyroid hormone level (105.9 pg/mL, NR 14.90–56.90 pg/mL), and decreased urine calcium excretion (2.45 mmol/24 h) were noted. This evidence concerns the gene PTH and hypercalcemia disease.
