[Lysosomal storage disorders - Fabry disease and Gaucher disease].

Lysosomal storage disorders (LSD) are a heterogenous group of inborn errors of metabolism due to lysosomal malfunction. LSDs affect 1 in 5000 live births, albeit every LSD itself has a low incidence. The most common LSDs are Fabry disease and Gaucher disease. The underlying cause mainly is an enzyme deficiency but may also be due to defects in transport or activation proteins, which result in progressive intra- and extra-lysosomal accumulation of undegraded storage material. The lysosomes play a key role in degradation and cellular recycling of macromolecules. Besides disturbance of cellular function, substrate accumulation may result in secondary toxic and/or inflammatory processes. For treatment of Fabry and Gaucher disease, several therapeutic approaches are approved including enzyme replacement therapy, chaperon therapy for Fabry disease and substrate reduction therapy for Gaucher disease.
