Overview
There is insufficient evidence to recommend routine screening for hypoparathyroidism. However, a significant number of patients of isolated idiopathic hypoparathyroidism with hypercalciuria may have a de novo calcium-sensing receptor (CASR) gene mutation. Molecular screening of CASR gene in patients with isolated idiopathic hypoparathyroidism with hypercalciuria is recommended during initial work-up as it has potentially important clinical relevance to the patient’s prognosis.
Screening
- There is insufficient evidence to recommend routine screening for hypoparathyroidism.
- However, a significant number of patients of isolated idiopathic hypoparathyroidism with hypercalciuria may have a de novo calcium-sensing receptor (CASR) gene mutation.[1]
- All patients require treatment with vitamin D3 supplementation for correction of hypocalcemia.
- As vitamin D3 supplementation may precipitate prolonged episode of hypercalciuria, the treatment decision should be evaluated on an individual basis in asymptomatic or mildly symptomatic patients.
- Molecular screening of CASR gene in patients with isolated idiopathic hypoparathyroidism with hypercalciuria is recommended during initial work-up as it has potentially important clinical relevance to the patient’s prognosis.[2]
