Hypercalcaemic disorders in children may present with poor feeding, hypotonia, lethargy, dehydration, vomiting, polyuria, failure to thrive, seizures and hypertension. The causes of hypercalcaemia in children, which can be classified as parathyroid hormone (PTH)-dependent or PTH-independent, are similar to those occurring in adults except that primary hyperparathyroidism and malignancy which the most common causes in adults, and account for >90% of adult patients with hype...

Background: Patients with autosomal dominant hypocalcemia type 1 (ADH1), due to germline gain-of-function calcium-sensing receptor (CASR) mutations, have hypocalcemia and seizures, hyperphosphatemia, hypercalciuria and inappropriately low parathyroid hormone (PTH) concentrations. Treatment for ADH1 comprises calcium and vitamin D analogs, however, their use predisposes to nephrocalcinosis and renal impairment. In contrast, recombinant human PTH(1-34) may incre...
