What this trial studies

This study follows the natural history of Albright hereditary osteodystrophy, focusing on patients with pseudohypoparathyroidism type 1A. It investigates the prevalence of growth hormone deficiency in these patients and evaluates the effects of growth hormone treatment on growth, weight, and overall health. Additionally, the study assesses neurocognitive and psychosocial aspects of the condition. The research aims to improve the quality of life for affected individuals by addressing both physical and psychological challenges associated with the disorder.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with pseudohypoparathyroidism type 1A who are either growth hormone deficient or meet specific criteria for growth hormone treatment.

Not a fit: Patients without a confirmed diagnosis of pseudohypoparathyroidism type 1A or those who do not meet the eligibility criteria will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved growth, weight management, and overall health for patients with pseudohypoparathyroidism type 1A.

How similar studies have performed: Previous studies have shown promising results in treating growth hormone deficiency in similar patient populations, indicating potential for success in this approach.

Eligibility criteria

Inclusion Criteria for GH study:

* Diagnosis of pseudohypoparathyroidism type 1A with mutation confirmation
* For the portion of the study in which growth hormone is used for participants who are not growth hormone deficient (ie., growth hormone sufficient), the participant must be over 3 years of age (ie., after 3rd birthday) AND also be pre-pubertal at the time of GH initiation.
* As of now, the growth hormone sufficient participants must meet the FDA-approved criteria for idiopathic short stature or the SGA indication.

Therefore, for all participants enrolling in the growth hormone portion of this study as of now, the growth hormone is used according to FDA-approved indications, and growth hormone use is according to standard of care clinical guidelines.
