Popis: Background : Gaucher disease (GD) is an autosomal recessive disorder produced by mutations in the glucocerebrosidase gene (GBA), causing storage of glucosylceramide in reticuloendothelial cells in multiple organs. Traditionally, the prediction of the phenotype based on the genotype has been reported to be limited. Subjects and Methods : We investigated the correlation between the enzymatic residual activity (ERA) and the phenotype at diagnosis of the disease in 45 GD Spanish patients (44 with type I and 1 with type III GD). The genotype involved two of the following previously expressed proteins: c.517A > C (T134P) , 1%; c.721G > A (G202R) , 17%; c.1090G > T (G325W) , 13.9%; c.1208G > A (S364N) , 4.1%; c.1226A > G (N370S) , 17.8%; c.1246G > A (G377S) , 17.6%; c.1289C > T (P391L) , 8.5%; c.1448T > C (L444P) , 3%; and c.1504C > T (R463C) , 24.5%. Recombinant alleles, deletion of 55 bp in exon 9 and 84GG mutation were considered as mutations with no residual enzymatic activity. Results : The ERA showed a statistically significant correlation with chitotriosidase ( P
