Familial hypocalciuric hypercalcaemia (FHH) is an autosomal dominant disorder characterized by lifelong elevation of serum calcium concentrations with inappropriately low urinary calcium excretion. Three types referred to as FHH1, FHH2 and FHH3 and located on chromosomes 3q21.1, 19p and 19q13.3, respectively, have been reported. FHH1, caused by loss-of-function mutations of the calcium-sensing receptor (CaSR), accounts for >65% of FHH patients. To identify the gen...

Familial hypocalciuric hypercalcaemia (FHH) comprises three types: FHH1, FHH2, and FHH3, which are due to mutations of the calcium-sensing receptor (CaSR), G-protein α 11 subunit (Gα11), and adaptor protein-2 sigma subunit (AP2σ), respectively. The aims of this study were: to assess for genotype–phenotype correlations among the three reported FHH3-causing AP2σ mutations, which all involve the Arg15 residue, and comprise Arg15Cys, Arg15His, and Arg15Leu...

Familial hypocalciuric hypercalcaemia (FHH) is an autosomal dominant disorder characterized by hypercalcaemia and inappropriately low urinary calcium excretion, and is occasionally associated with acute pancreatitis. FHH can be classified into three types: FHH type 1, caused by loss-of-function mutations of the calcium-sensing receptor (CaSR), which accounts for >65% of cases; FHH type 2, due to loss-of-function mutations of the G-protein α 11 subunit (Gα11), of ...
