Natural History, Complications, and Prognosis
Natural History
- The symptoms of (disease name) usually develop in the first/ second/ third decade of life, and start with symptoms such as ___.
- The symptoms of (disease name) typically develop ___ years after exposure to ___.
- If left untreated, [#]% of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
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.[1]
- Very rarely FHH is associated with[2][3][4]
Prognosis
- Prognosis is similar to the general population in patients with familial hypocalciuric hypercalcemia.[5]
