Recommended testing in guidelines on BioMet - Bowron & Olpin (2012). Glycogen storage disease IV - cardiomyopathy seen in subset of patients - particularly the early infant onset. - OMIM. 43 DM variants on HGMD, variable onset, only one as neonatal onset but quite a few reports discuss paediatric onset. Cardiomyopathy does not seem to be a key presenting feature.
