Introduction: Hypophosphatasia (HPP) is the rare, inherited, metabolic disease with broad-ranging severity caused by inactivating mutation(s) in the tissue-nonspecific alkaline phosphatase (TNSALP) gene. In the childhood form of HPP, there are mineralization defects of the bones and teeth, often with impaired physical function, muscle weakness, and decreased growth. We previously reported sustained radiographic improvement in rickets compared to historical controls in 5–1...

Background: Hypophosphatasia (HPP) is the rare inherited metabolic disorder resulting from loss-of-function mutation(s) in the tissue-nonspecific alkaline phosphatase (TNSALP) gene. TNSALP deficiency can cause a spectrum of complications in children including premature deciduous tooth loss, rickets, poor growth, and compromised physical function. We previously reported that children, 5–12 years old, with HPP and treated with asfotase alfa, a recombinant bone-targeted huma...
