Primary Outcome Measures:
  • Frequency of hypoparathyroidism, pseudohypoparathyroidism and autosomal dominant hypocalcaemia and its consequences [ Time Frame: One year ]

    The prevalence of kidney-, cardiovascular- and neuropsychiatric disease, fertility, hospitalization required hypo- or hypercalcaemia, overall number of hospitalizations and mortality.
