How is Pseudopseudohypoparathyroidism diagnosed?
Diagnosis. The diagnosis is based on the presence of the Albright hereditary osteodystrophy pseudotype but without the PTH resistance. Blood tests including calcium, phosphate, and PTH will exclude other forms of pseudohypoparathyroidism. X-rays may reveal a short fourth metacarpal.
What is pseudo pseudo?
“Pseudo-” indicates something false, deceptive, counterfeit, spurious—in other words, not “real,” At first glance we might think that “pseudo-” meant “not,” so that “pseudo-pseudo-” would present a double negative, and pseudo-pseudohypoparathyroidism might be no more than the original hypoparathyroidism.
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.
What is Pseudohypoparathyroidism Type 1A?
Pseudohypoparathyroidism type 1A (PHP1A) is a type of pseudohypoparathyroidism. Pseudohypoparathyroidism occurs when your body is unable to respond to parathyroid hormone, a hormone that controls the levels of calcium, phosphorous, and vitamin D in the blood.
What is secondary parathyroid disease?
Secondary hyperparathyroidism is a condition in which a disease outside of the parathyroid glands causes all of the parathyroid glands to become enlarged and hyperactive. The most common causes of secondary hyperparathyroidism are kidney failure and vitamin D deficiency.

What does pseudo mean in medical terms?
A prefix meaning false or spurious (e.g. pseudochalazion, pseudoglaucoma, pseudopapilloedema, etc.).
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.
How is pseudohypoparathyroidism diagnosed?
Diagnosis. 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 PTH (pseudohypoparathyroidism)?
Pseudohypoparathyroidism (PTH) is a genetic disorder in which the body is unable to respond to parathyroid hormone. Parathyroid hormone helps control calcium, phosphorous, and vitamin D levels in the bones and blood.
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.
