The response to exogenous parathyroid hormone (PTH) with urinary excretion of phosphate and cyclic adenosine monophosphate (cAMP) was tested by the use of synthetic human parathyroid hormone (1-34) [hPTH-(1-34)] on 59 patients with hypocalcemia and normal or high serum inorganic phosphorus and
OBJECTIVE
The GNAS gene encodes the alpha-subunit of stimulatory G proteins, which play a crucial role in intracellular signal transduction of peptide and neurotransmitter receptors. In addition to transcript variants that differ in their first exon due to different promoters, there are two long
The diagnosis of acrodysostosis has been differentiated from that of pseudohypoparathyroidism or pseudo-pseudohypoparathyroidism by the absence of endocrine abnormalities, more generalized osseous abnormalities, and a characteristic facial appearance. Two cases are presented which fulfill all of the
Pseudopseudohypoparathyroidism and pseudohypoparathyroidism have been thought to represent variants of the same disease process, Albright hereditary osteodystrophy. A 31-year-old woman with the characteristic features of pseudopseudohypoparathyroidism, such as shortened metacarpals and metatarsals,
Forty patients with hypocalcemia and/or Albright's hereditary osteodystrophy were studied. Based on the estimation of serum calcium and parathyroid hormone (PTH) levels as well as the urinary cAMP response to infusions with parathyroid extract, it was possible to classify all of the patients studied
A family consisting of a mother, a father with probable pseudopseudohypoparathyroidism (PPHP), two normal daughters, and four daughters with pseudohypoparathyroidism (PHP) have been observed for more than 15 years at North Carolina Memorial Hospital (NCMH). The studies performed on family members
Pseudohypoparathyroidism (PHP) is a hereditary disorder with typical dysmorphic signs, oligophrenia and clinical and laboratory signs of hypoparathyroidism, which is resistant to parathyroid extract (PTE). Pseudopseudohypoparathyroidism (PPHP) is a genetically identical, partial form of PHP without
Albright hereditary osteodystrophy (AHO) is a complex disorder defined by the presence of a short adult stature relative to the height of an unaffected parent and brachydactyly type E, as well as a stocky build, round face, and ectopic calcifications. AHO and pseudohypoparathyroidism (PHP) have been
We examined a German family with five members affected by Albright hereditary osteodystrophy (AHO). The only patient with pseudohypoparathyroidism type Ia (PHP-Ia) presented clinically with latent tetany, mental retardation, round face, short stature, brachymetacarpia and calcifications of
Albright's hereditary osteodystrophy has been diagnosed in a 35-year-old woman who presented recurrent cutaneous ossifications of the auricular area. The patient exhibited other cutaneous ossifications, a short stature with obesity, round face, stocky hands and feet, radiological calcifications of
Urinary excretion of cyclic adenosine 3',5'-monophosphate (3',5'-AMP) was tested in normal subjects and patients with pseudohypoparathyroidism, idiopathic hypoparathyroidism, surgical hypoparathyroidism, and pseudopseudohypoparathyroidism under basal conditions and after a 15 min infusion of
