HPOsFreeText: Elevated Glc4 urine levels present, She was antibody negative to rhGAA, Initially she tolerated ERT and ITI however complications occurred midway through the second round, Tracheostomy since age 7 months required, By about age 5 years, she communicated primarily via nonverbal means, gesturing with her right hand, and to a minimal extent, with closure of her eyes and movements of mouth, After degrading severely she was started on IVIG which led to a drop in antibody titers and improvement in her health over time
