The initial hormonal panel was normal for the thyroid profile, but high serum calcium (of 3.11 mmol/L; normal ranges between 2.2 and 2.55 mmol/L) and PTH (of 152 pg/mL; normal ranges between 10 and 65 pg/mL) represented the biological confirmation of a primary hyperparathyroidism. The gene discussed is PTH; the disease is primary hyperparathyroidism.
