Nov 19th, 2021 - Pseudohypoparathyroidism type Ib (PHP1B) is characterized by hypocalcemia and hyperphosphatemia due to PTH-resistance in the proximal renal tubules. Maternal pathogenic STX16/GNAS variants leading to maternal epigenetic GNAS changes impair express...

Nov 7th, 2021 - Sporadic pseudohypoparathyroidism type 1B (sporPHP1B) is an imprinting disease without a defined genetic cause, characterized by broad methylation changes in differentially methylated regions (DMRs) of the GNAS gene. This work aims to provide insi...

Oct 11th, 2021 - Hypoparathyroidism (HypoPT) or pseudo-hypoparathyroidism (pseudo-HypoPT) during pregnancy may cause maternal and fetal/neonatal complications. In this regard, only a few case reports or case series of pregnant or lactating women have been publishe...

Oct 7th, 2021 - GNAS encodes the Gαs (stimulatory G-protein alpha subunit) protein, which mediates G protein-coupled receptor (GPCR) signaling. GNAS mutations cause developmental delay, short stature, and skeletal abnormalities in a syndrome called Albright's her...

Sep 28th, 2021 - Pseudohypoparathyroidism (PHP) is a rare, genetic disorder caused by impaired stimulatory G protein (Gsα) signaling through downregulation of the gene, GNAS. The resultant hormone abnormalities can be treated with hormone replacement therapy, but ...

Sep 28th, 2021 - Pseudohypoparathyroidism (PHP) is a rare, genetic disorder caused by impaired stimulatory G protein (Gsα) signaling through downregulation of the gene, GNAS. The resultant hormone abnormalities can be treated with hormone replacement therapy, but ...

May 27th, 2021 - Pseudohypoparathyroidism type 1A (PHP1A) is a rare, genetic disorder caused by impaired stimulatory G-protein signaling due to heterozygous mutations in the gene, GNAS. The most severe form of the disease, PHP1A occurs when a GNAS mutation is inhe...

Oct 24th, 2018 - It is an open label intervention study for the off-label use of theophylline in psuedohypoparathyroidism (PHP).Theophylline is a is non-specific phosphodiesterase inhibitor which increases the levels of secondary messenger,cAMP. PHP patients have ...

Aug 22nd, 2018 - Pseudohypoparathyroidism 1a (PHP1a) is a disorder that is associated with many endocrine problems. People with PHP1a are at risk for the development of obesity. The objective of the study will help determine if obesity is related to abnormalities ...

Jun 26th, 2017 - Study measures will be done at baseline and during a 24h infusion of IV theophylline. Theophylline levels will be drawn to ensure therapeutic dosing and to monitor for toxicity. Measures include laboratory values, response to PTH infusion and rest...

Oct 6th, 2021 - GNAS mutations in kids with severe obesity may go undetected, researchers suggested. In a study of 2,548 children with severe obesity in whom genetic causes of obesity were not suspected, a total of 22 were found to have heterozygous GNAS mutation...

Jan 14th, 2016 - On initial presentation, exclusion of other diseases that result in a similar "bright bone" appearance on radiography is important. The causes of diffuse osteosclerosis include hypervitaminosis D, hypoparathyroidism, myelofibrosis, Paget disease, ...
