Adult-onset glycogen storage disease type II (GSD-II), unlike the infantile form, is not normally associated with coexisting cardiovascular pathologies. In infantile onset GSD-II, cardiomyopathy is a common feature, and mutations in the genes for cardiac troponin T and I are likely to be involved. This case report describes a 39-year-old man with no classical risk factors for premature cardiac disease who presented with central chest pain and shortness of breath. Serum aspartate transaminase (AST) had been consistently elevated for 15 years. Adult GSD-II had been diagnosed two years previously by muscle biopsy. On presentation, there was an elevated serum creatine kinase and AST. Electrocardiography and echocardiography were both normal, and an acute coronary syndrome was ruled out. Cardiac Troponin T (cTnT) was found to be positive at 0.1 microg/L using a Cardiac Reader, subsequently confirmed on an Elecsys 1010 (both from Roche Diagnostics, Lewes, UK). cTnT may therefore be a useful biomarker in examining subclinical cardiac involvement in GSD-II patients.
