Background: Neonatal severe hyperparathyroidism (NSHPT) is a rare disorder caused by inactivating calcium-sensing receptor (CASR) mutation characterized by striking hyperparathyroidism leading to severe hypercalcemia. Heterozygous loss of function in CASR gives rise to a benign variant called familial hypocalciuric hypercalcemia which needs no treatment. We are reporting 3 cases of NSHPT due to inactivating homozygous CASR mutation n...
