Alterations in calcium metabolism caused by familial hypocalciuric hypercalcemia (FHH). Hypercalcemia arises due to an increase in the parathyroid set-point for parathyroid hormone (PTH) release and possibly also from decreased renal calcium excretion (11, 12). Alterations in bone metabolism are not usually observed in FHH (13).
