ICD-11 code : 5A51.2;
Preferred Label : Familial hypocalciuric hypercalcaemia;
ICD-11 definition : Familial Hypocalciuric Hypercalcaemia (FHH) or benign familial hypercalcaemia is an
autosomal dominant disorder of calcium metabolism that is often asymptomatic and that
is biologically characterised by a significant but moderate hypercalcaemia. Serum
levels of parathyroid hormone are normal or slightly increased, and urinary calcium
excretion is relatively low for hypercalcaemia. CASR, GNA11 and AP2S1 have been identified
as causative genes.;
