Background. Hypophosphatasia (HPP) is caused by loss-of-function mutation(s) of the gene that encodes the tissue-nonspecific isoenzyme of alkaline phosphatase (TNSALP). Consequently, cell-surface deficiency of TNSALP phosphohydrolase activity leads to extracellular accumulation of inorganic pyrophosphate, a natural substrate of TNSALP and inhibitor of(More)
Hypophosphatasia (HPP) is a rare inborn error of metabolism resulting in undermineralization of bone and subsequent skeletal abnormalities. The natural history of HPP is characterized by rickets and osteomalacia, increased propensity for bone fracture, early loss of teeth in childhood, and muscle weakness. There is a wide heterogeneity in disease(More)
