What does Pseudopseudohypoparathyroidism mean?

Pseudopseudohypoparathyroidism (PPHP) is an inherited condition that causes short stature, round face, and short hand bones.[3223][10875] PPHP causes joints and other soft tissues in the body to harden. It also affects how bones are formed.

What is the difference between pseudohypoparathyroidism and Pseudopseudohypoparathyroidism?

Pseudopseudohypoparathyroidism and pseudohypoparathyroidism both involve the same GNAS gene, but pseudopseudohypoparathyroidism has normal calcium homeostasis because of the normal maternal allele in the kidney.

How is pseudohypoparathyroidism diagnosed?

Pseudohypoparathyroidism can be diagnosed by blood or urine tests to measure the levels of calcium, phosphorous, and parathyroid hormone . If the levels of parathyroid hormone and phosphorous are high and if the levels of calcium or low, this indicates the possibility of pseudohypoparathyroidism.

What is pseudo hyperparathyroidism?

Pseudohypoparathyroidism (PHP) is a genetic disorder in which the body fails to respond to parathyroid hormone. A related condition is hypoparathyroidism, in which the body does not make enough parathyroid hormone.

How do you say Pseudopseudohypoparathyroidism?

3. Synonyms for pseudopseudohypoparathyroidism. Albright hereditary osteodystrophy-PPHP syndrome.

What are the symptoms of Pseudohypoparathyroidism?

Pseudohypoparathyroidism is characterized by short stature, a round face, short neck, and shortened bones in the hands and feet. Intelligence usually ranges from low normal to mentally retarded. Headaches, weakness, tiring easily, lethargy, cataracts and blurred vision or hypersensitivity to light may also be present.

Is Pseudopseudohypoparathyroidism genetic?

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.

What causes Pseudopseudohypoparathyroidism?

PHPP is caused by mutations in the GNAS gene and is inherited in an autosomal dominant fashion. This condition is usually inherited from the father (genomic imprinting).

How common is Pseudohypoparathyroidism?

Pseudohypoparathyroidism is a very rare disorder, with estimated prevalence between 0.3 and 1.1 cases per 100000 population depending on geographic location.

Why do I have knuckle dimples?

AHO has been genetically linked to GNAS1 gene. Brachydactyly most commonly involves the fourth and fifth metacarpals, but can also be seen in other metacarpals and metatarsals. Affected knuckles dimple when the fist is clenched causing the ‘Knuckle–dimple’ sign (Figures 2 and 3).

How is pseudohypoparathyroidism (PHP) diagnosed?

Diagnosis of PPHP is based on the presence of features of Albright hereditary osteodystrophy (AHO) without parathyroid hormone (PTH) resistance. If there are features of AHO and resistance to PTH a different form of pseudohypoparathyroidism (PHP) will be considered.

What is the prognosis of pseudopseudohypoparathyroidism?

A male with pseudohypoparathyroidism has a 50% chance of passing on the defective GNAS gene to his children, although in an imprinted, inactive form. Any of his children receiving this gene will have pseudopseudohypoparathyroidism.

How can pseudopseudohypoparathyroidism be passed from father to child?

Any of his children receiving this gene will have pseudopseudohypoparathyroidism. Any of his daughters that have pseudopseudohypoparathyroidism may in turn pass along pseudohypoparathyroidism 1A to her children as the imprinting pattern on the inherited paternal gene will be changed to the maternal pattern in the mother’s ovum during meiosis.

What happens when the parathyroid gene is not working properly?

When this gene is not working correctly, the body is not able to properly respond to parathyroid hormone, which increases the level of phosphorous in the blood and decreases the level of calcium. A mutation in this gene is most often inherited from the affected person’s mother, although it can sometimes be inherited from the father.
