XLH is the most common heritable form of rickets/osteomalacia in the United States. The disorder is characterized by renal phosphate wasting, rickets and limited growth in childhood. Osteomalacia and fractures occur in adults. At all ages and irrespective of treatment there is a high incidence of secondary hyperparathyroidism.

We hypothesize that elevated PTH levels may significantly contribute to the skeletal disease in XLH. We are presently conducting clinical studies that examine this idea in two ways.
