Hypophosphatasia is a rare disease caused by mutations in the gene encoding tissue- nonspecific isoenzyme of alkaline phosphatase. Duplications of the ALPL gene account for fewer than 1% of the mutations causing HPP. It has been shown that asfotase alfa treatment mineralizes the skeleton and improves respiratory function and survival in severe forms of hypophosphatasia.The newborn was evaluated for respiratory failure and generalized hypoton...
