Discover answers to frequently asked questions and a collection of publications, resources and programs to learn more about research, treatments and living life well with HPP.
Hypophosphatasia or HPP is a rare, genetic, metabolic disorder where alterations in the TNSALP gene lead to low alkaline phosphatase activity, and is characterized by soft, weak bones and a form of osteomalacia. Made in the liver, bone and kidney, TNSALP is necessary for muscle metabolism and to mineralize bones and teeth. The defective mineralization can lead to muscle weakness, achy bone pain, fractures, early tooth loss, lack of cementum, and in its severe form, death.
