Bone mineral density in patients with familial hypocalciuric hypercalcaemia (FHH).

Abstract

Chronic hypercalcaemia in affected members of families with FHH is not the result of an increase rate of bone mineralisation, because they have normal bone mass. They seem to be relatively insensitive to the deleterious effects of PTH on bone mineral state, because raised concentrations of PTH were not associated with reduced bone mass.
