The disease is autosomal recessive inherited and is clinically and genetically heterogenous. The authors describe a 30- year- old woman affected by late- onset Pompe disease with vascular affection resembling atherosclerotic angiopathy of the elderly. Genetic analysis revealed two novel mutations (Ala237Val and Gly293Arg) in the acid α - glucosidase gene in this patient.展开更多
