PROJECT NARRATIVE Infantile Pompe Disease (IPD) is a glycogen storage disorder caused by a deficiency of acid alpha- glucosidase (GAA) that, without treatment, leads to death by cardiorespiratory failure within the first two years of life. The only treatment currently available is enzyme replacement with recombinant GAA, but many patients develop anti-therapeutic antibodies (ATA) that render the therapy ineffective. This project proposes the development and validation of a diagnostic tool to identify patients who are at high risk of developing treatment-limiting ATA using personalized genetic information, with the goal of assisting clinicians to tailor the implementation of immune-suppressive therapy with potential long-term adverse effects to only those IPD patients at higher risk of developing ATA.
