Background: Many factors influence serum calcium concentration, but the major determinants of calcium homeostatsis are parathyroid hormone (PTH), vitamin D, the ionized calcium, and phosphate [1]. Therefore, deranged calcium metabolism is often seen in the presence of disordered parathyroid hormone (PTH) and/or vitamin D actions. Among these causes is end-organ resistance to the biological effect of parathyroid hormone.
Case Report: In this paper, we report a case of a patient who presented with flu like symptoms and incidental finding of hypocalcemia that is consistent with parathyroid hormone resistance.
Conclusions: Familial causes of hypocalcemia, although rare, should be thought about after ruling out the other common causes of hypocalcemia.
