Gaucher disease is caused by glucocerebroside accumulation in different tissues due to beta-glucocerebrosidase enzyme deficiency. Genetic defects in proteins involved in beta-glucocerebrosidase processing and activation may indirectly lead to Gaucher-like phenotypes in affected individuals. Saposin C, derived from the prosaposin precursor, is a crucial activator for beta-glucocerebrosidase, and its deficiency has been linked to Gaucher-like phenotypes in several clinical reports.
