Official Title: Altered Resting Energy Expenditure as a Cause of Obesity in Pseudohypoparathyroidism 1a: A Pilot Study
Brief Summary: The investigators would like to learn more about the metabolic consequences of pseudohypoparathyroidism type 1a in children, adolescents and adults with this condition. People with pseudohypoparathyroidism 1a are at risk for development of obesity. To better understand the cause of overweight or obesity, investigators are measuring body composition and resting energy expenditure (REE), which is the amount of calories burned while completely at rest. The investigators also want to determine the amount of body fat.
