HPP: a life-threatening metabolic disorder1,3
HPP ruins lives with high mortality rates in infants and systemic sequelae that can increase the risk of death in juvenile and adult patients.1,4-8
HPP ruins bones and bodies1,2
Low ALP is the underlying cause of morbidities and mortality associated with HPP.1,2,9
How to accurately identify HPP
Misdiagnosis can lead to inappropriate—and sometimes harmful—treatment that can compound clinical consequences, so it's important to know what the common misdiagnoses for HPP are and how to easily confirm your suspicion of the disease.1,6,10,11
