Official Title: Study of Growth Hormone Use in Patients With Pseudohypoparathyroidism Type 1a and Assessment of Cognitive/Behavioral Status in Albright Hereditary Osteodystrophy

Brief Summary:

We, the researchers, have found that growth hormone deficiency is very common in patients with pseudohypoparathyroidism type 1a, which falls under the broader condition termed Albright hereditary osteodystrophy. Patients with pseudohypoparathyroidism type 1a typically are short and obese. Some of these patients are not short during childhood, but due to a combination of factors, they end up short as adults. We are evaluating the effect of growth hormone treatment in those patients with pseudohypoparathyroidism type 1a who are found to be growth hormone deficient. We hypothesize that growth hormone deficiency may contribute to the short stature and obesity found in this condition. We are also evaluating the effect of growth hormone on patients with pseudohypoparathyroidism type 1a who are not growth hormone deficient (i.e., growth hormone sufficient) in those who had been on study drug through R01 FD003409 or who meet the criteria of idiopathic short stature or SGA.

We are also evaluating neurocognitive and psychosocial functioning in participants with AHO in order to determine the specific impairments that are most common in the condition and to determine the best approach toward management.
