Dr. Byrne is currently conducting numerous clinical research studies for a variety of rare diseases, with specific attention to developing therapies for inherited muscle disease. As a pediatric cardiologist, his focus is on conditions that lead to skeletal muscle weakness, cardiac dysfunction and respiratory dysfunction. His research team has made significant contributions to the understanding and treatment of Pompe disease, a type of muscular dystrophy resulting from abnormal glycogen accumulation in the muscle. His current research has focused on developing new therapies using the missing cellular protein or the corrective gene to restore muscle function in Pompe, Duchenne muscular dystrophy and other inherited myopathies.
