The purpose of this study is to identify the number of persons in Denmark with the diagnose hypoparathyroidism, autosomal dominant hypocalcaemia or pseudohypoparathyroidism. Also the investigators want to identify the causes and symptoms of these patients and their prognosis.
||Hypoparathyroidism, Autosomal Dominant Hypocalcaemia and Pseudohypoparathyroidism in Denmark - Epidemiology, Causes, Symptoms and Prognoses
Biospecimen Retention: None Retained
Primary Outcome Measures:
- Frequency of hypoparathyroidism, pseudohypoparathyroidism and autosomal dominant hypocalcaemia and its consequences [ Time Frame: One year ] [ Designated as safety issue: No ]
