Clin Chem ;38 1: Alkaline phosphatase is characteristically elevated in children, especially during periods of rapid growth, and usually returns to normal in adulthood with or without treatment.

Similar to that of calcium, homeostasis of phosphorus also involves direct participation of the intestine, bones, and kidneys, being maintained by the action of Vitamin D 1. DMP1 mutations in autosomal recessive hypophosphatemia implicate a bone matrix protein in the regulation of phosphate homeostasis. Hypophosphatemia in the emergency nelnatal therapeutics.

The redistribution condition, for its part, besides being more frequent in these patients, is commonly responsible for triggering the more severe form of hypophosphatemia. The hipfosfatemia spectrum of X-linked hypophosphatemia XLH ranges from isolated hypophosphatemia to severe lower-extremity bowing. More detailed information for clinicians ordering genomic testing can be found here.
