Pompe disease (PD) is a rare and fatal neuromuscular disease, which is an autosomal recessive disorder. This is the first study to report a case of the compound heterozygous c.1822C>T and c.2297A>C mutations of the GAA gene in mainland Chinese patient, which led to the classic infantile-onset Pompe disease (IOPD) characterized by hypertrophic cardiomyopathy. This case highlights that the detection of GAA activity in peripheral blood by dried blood spot and GAA gene analysis can clarify the diagnosis of IOPD and provides the genetic counseling to those parents whose children have IOPD for giving birth in the future. Although PD is rare, and universal screening has not yet been established, we suggest that clinicians should consider the possibility of Pompe in the presence of hypertrophic cardiomyopathy.
