Sommario
L’ipofosfatasia è una malattia multi-sistemica, causata da mutazioni inattivanti del gene ALPL codificante la fosfatasi alcalina, il cui quadro clinico può esordire a diverse età e progredire nel tempo. Il fenotipo clinico presenta in genere una severità inversamente correlata all’età di insorgenza. Da alcuni anni è disponibile una terapia enzimatica sostitutiva che si è dimostrata efficace e sicura, in particolare nelle forme neonatali, infantili e giovanili.
