Familial hypocalciuric hypercalcemia natural history, complications and prognosis
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Ajay Gade MD[2]]
Overview
Overview
Patients with familial hypocalciuric hypercalcemia are asymptomatic but rarely can present with signs and symptoms of hypercalcemia. Very rarely familial hypocalciuric hypercalcemia can cause complications such as pancreatitis, gallstones, chondrocalcinosis. Prognosis is excellent and patients with FHH have a normal lifespan.

Natural History, Complications, and Prognosis
Natural History
Patients with familial hypocalciuric hypercalcemia are asymptomatic but rarely can present with signs and symptoms of hypercalcemia.[1]
Complications
- The complications associated with primary hyperparathyroidism, like osteopenia and nephrolithiasis, is not increased in persons with benign familial hypocalciuric hypercalcemia, and the rates are similar to those in the general population.
- Rarely, a severe form of this disease, neonatal severe primary hyperparathyroidism is seen in infants with homozygous CASR mutations.[2]
- Very rarely FHH is associated with:[3][4][5]
Prognosis
Prognosis is good with a lifespan similar to the general population, in patients with familial hypocalciuric hypercalcemia.[6]
