It was concluded that higher serum concentrations of PTH do not account for the lower renal clearance of calcium and magnesium in FHH calcium concentration, the group with FHH showed indices suggesting lower circulating PTH activity than the group with 1HPT.

The differences in cAMP response to PTH between FHH and 1HPT patients could be secondary to differences in circulating PTH concentrations (these are lower in subjects with FHH) or could reflect a renal lesion more closely related to the underlying etiology of FHH.

Serum concentrations of calcium, magnesium, phosphate, and immunoassayable parathyroid hormone, urinary calcium excretion, and the rate of renal tubular reabsorption of phosphate were measured; the findings were compared with results in 10 patients with primary hyperparathyroidism matched for serum calcium concentration to establish differences between the diseases.

Thus, we studied 29 patients with FBH from 11 families, 29 age- and sex-matched controls, and 42 patients with primary hyperparathyroidism (1 degree HPT), measuring PTH with a highly sensitive two-site immunochemiluminometric assay and the hypercalcemic tumor factor PTH-related peptide (PTHrP) with an extraction/concentration RIA.

To better define the abnormalities of parathyroid function in FBH and primary hyperparathyroidism (1 degree HPT), we used a two-site immunochemiluminometric assay for intact PTH to examine PTH suppressibility in normal individuals and patients having FBH or 1 degree HPT.

We conclude that 1) the hypercalcemia due to constitutive overactivity of the PTH/PTHrP receptor is indistinguishable from that of mild primary hyperparathyroidism in clinical characteristics and renal tubular and skeletal features; and 2) the classic laboratory manifestations of primary hyperparathyroidism, with the possible exception of osteitis fibrosa cystica, can all be accounted for by overactivity of a single receptor.

However, the demonstration of LOH at 11q13 and MEN1 gene mutations in small parathyroid adenomas of patients with slight hypercalcemia and normal serum PTH levels suggest that altered MEN1 gene function may also be important for the development of mild sporadic pHPT.
