The purpose of this study is to evaluate the effect of growth hormone treatment on phosphorus levels in the body. Phosphorus is an important mineral for bone growth. It is well known that growth hormone treatment improves bone density and bone mineral content. The amount of phosphorus is maintained by the kidneys. Fibroblast Growth Factor 23 has recently been recognized to help kidneys control phosphate levels.

Patient ages 3-14 years receiving growth hormone for growth hormone deficiency or short stature
Children with normal stature ages 3-18 years.
This study will compare Fibroblast Growth Factor 23 levels in children with and without growth hormone deficiency. Children with growth hormone deficiency will have levels taken before starting growth hormone replacement and after it has been initiated.
|Ages Eligible for Study:
||3 Years to 14 Years
