Pseudohypoparathyroidism - Wikipedi

Pseudopseudohypoparathyroidism (PPHP) is an inherited condition that causes short stature, round face, and short hand bones. PPHP causes joints and other soft tissues in the body to harden. It also affects how bones are formed. As a result, PPHP can cause bone, joint, and nerve damage, and this damage can cause lasting pain. Some people with PPHP (10%) also have learning disability Pseudopseudohypoparathyroidism (PPHP) is an inherited disorder, named for its similarity to pseudohypoparathyroidism in presentation. It is more properly Albright hereditary osteodystrophy although without resistance of parathyroid hormone frequently seen in that affliction. The term pseudopseudohypoparathyroidism is used to describe a condition where the individual has the phenotypic. Pseudohypoparathyroidism. Pseudohypoparathyroidism (PHP) is defined as resistance to the actions of parathyroid hormone (PTH), primarily in the renal proximal tubule where PTH acts to stimulate the production of 1, 25 dihydroxyvitamin D (1,25(OH)2D) and to prevent reabsorption of phosphate leading to increased urinary phosphate excretion Pseudohypoparathyroidism (PHP) is a condition where there is end-organ resistance to parathyroid hormone (PTH). Epidemiology Pseudohypoparathyroidism has an estimated prevalence of 1.1 per 100,000 people 6. Clinical Presentation Hypocalcemia.

Pseudohypoparathyroidism is a hereditary disorder characterized by an inadequate response to the parathyroid hormone, although the hormone is present in normal amounts. This inadequate response affects bone growth in individuals with Pseudohypoparathyroidism. Affected individuals may also experience headaches, unusual sensations, weakness, easy.

This defect appears to represent a failure of intracellular reception of the cyclic AMP message, and the disorder might be called pseudohypoparathyroidism Type II. (N Engl J Med 289:1056-1060, 1973 Pseudohypoparathyroidism type 1A is a rare, autosomal dominant syndrome caused by loss-of-function mutation in the GNAS1 gene. It specifically requires maternal transmission of the mutation to result in this clinical syndrome. This mutation leads to an inability to activate adenyl cyclase when parathyroid hormone (PTH) binds to its receptor Abstract. Pseudohypoparathyroidism exemplifies an unusual form of hormone resistance as the underlying molecular defect is a partial deficiency of the alpha subunit of the stimulatory G protein (G(s)alpha), a key regulator of the cAMP signalling pathway, rather than of the parathyroid hormone (PTH) receptor itself To diagnose pseudohypoparathyroidism type I, intravenous human PTH (1-34) infusions were performed; however, they showed brisk responses of plasma and/or urine cyclic AMP in response to the PTH infusion, but the phosphaturic response to the PTH was sluggish compared to the controls Abstract. Objective: Disorders caused by impairments in the parathyroid hormone (PTH) signalling pathway are historically classified under the term pseudohypoparathyroidism (PHP), which encompasses rare, related and highly heterogeneous diseases with demonstrated (epi) genetic causes
