Common in Finland; only sporadically described in Central Europe or North America.
EtiopathogenesisThis section has been translated automatically.
Autosomal recessive inherited defect of aspartyl glucosaminidase mapped on the gene locus 4q32-q33 Pathogenetically, there is a lack of activity of the lysosomal enzyme aspartyl glucosaminidase (exoglycosidase), with consecutive deposition of glycoproteins in the lysosomes of the cells of the vascular intima and neuronal tissues.
