Hypophosphatemic Rickets with Hypercalcemia
Hypophosphatasia is a inborn metabolic disorder of the bones characterized by skeletal defects resembling those of rickets. The symptoms result from a failure of bone mineral to be deposited in young, uncalcified bone (osteoid), and in the cartilage at the end of the long bones (epiphyses) during early years. The activity of the enzyme alkaline phosphatase in blood serum and bone cells is lower than normal. Urinary excretion and blood plasma concentrations of phosphoethanolamine and inorganic pyrophosphate are abnormally high. Unlike other forms of rickets, Hypophosphatasia does not respond to treatment with vitamin D.
