Background: Hypophosphatasia (HPP) is a rare metabolic bone disease caused by loss-of-function mutations in the gene ALPL encoding the tissue nonspecific alkaline phosphatase. HPP is associated with significant morbidity and mortality in pediatric patients, with high rates as high as %100 in perinatal-onset HPP. Serum alkaline phosphatase (ALP) activity is markedly reduced, which leads to increased serum/urine phosphoethanolamine (PEA), pyridoxal-5’phosphate (PLP). Asfota...
