|Condition or disease||Intervention/treatment||Phase|
|Autosomal Dominant Hypophosphatemic Rickets||Dietary Supplement: Iron||Not Applicable|
Iron will be provided in an open label treatment to all enrolled subjects. Iron levels will be monitored in blood and doses adjusted with the target of getting the iron levels to or a little above 100 mcg/dl.
The study will look to see if there is a decrease of FGF23 level. It will also look at how long does it take to decrease the level of FGF 23 and how long it takes for the serum and urine phosphate to normalize.

Experimental: iron supplements
all subjects will receive iron supplementation based on iron levels in blood
Dietary Supplement: Iron
All subjects will receive iron supplementation based on iron levels in the blood
- Does increasing serum iron concentrations above 100 mcg/dl in patients with ADHR result in a decrease in intact FGF23. [ Time Frame: FGF23 will be measured at 1, 2, 3, 6, 9, and 12 months ]Perform a pilot study in ADHR patients with low serum iron concentrations (defined below) to determine if increasing serum iron concentrations above 100 mcg/dl results in a decrease in intact FGF23 (primary endpoint) and C-terminal FGF23 concentrations by at least 20% and normalizes serum phosphorus and TMP/GFR (tubular maximum phosphate reabsorption/ glomerular filtration rate) within 6 months of attaining goal iron concentrations.
