Phenotype

Built up Gb3 and glycosphingolipids may lead to heart attack and stroke

As almost each family has its own private mutation, phenotypes of affected persons can be very variable. In general, with increasing age symptoms become more severe. This effect is due to more and more accumulated glycosphingolipids that cannot be converted by the dysfunctional enzyme. The built up globotriaoslyceramide (Gb3) and related glycosphingolipids in the lysosomes, tissues, blood vessels and organs lead to a malfunction of major organs in the body starting at an age of 30 - 35 (see picture on the right). Thus untreated patients die approximately 10 - 20 years early (females and males, respectively).
