Background: Gaucher disease (GD) is a genetic disease caused by mutations in the GBA1 gene which result in reduced enzymatic activity of β-glucocerebrosidase (GCase). This study identified the progranulin (PGRN) gene (GRN) as another gene associated with GD. Methods: Serum levels of PGRN were measured from 115 GD patients and 99 healthy controls, whole GRN gene from 40 GD patients was sequenced, and the genotyping of 4 SNPs identified in GD patients was performed in 161 GD and 142 healthy control samples. Development of GD in PGRN-deficient mice was characterized, and the therapeutic effect of rPGRN on GD analyzed. Findings: Serum PGRN levels were significantly lower in GD patients (96.65 ± 53.45 ng/ml) than those in healthy controls of the general population (164.99 ± 43.16 ng/ml, p
