The carbohydrate-deficient glycoprotein (CDG) syndrome in its most severe form (neonatal olivopontocerebellar atrophy) is a life-threatening multisystem disease. We report a neonate who was referred for cardiological assessment because of respiratory distress, a murmur and episodes of desaturation. After initial spontaneous improvement he presented at 9 weeks with evidence of a severe hypertrophic obstructive cardiomyopathy (HOCM). The diagnosis of CDG syndrome was suggested by the characteristic dysmorphic features, hypotonia, visual inattention and severe failure to thrive; it was confirmed by electrophoresis of serum transferrin. HOCM can be a feature of the CDG syndrome, in addition to the (previously reported) pericardial effusions.
