[[http://www.uniprot.org/uniprot/GLCM_HUMAN GLCM_HUMAN]] Defects in GBA are the cause of Gaucher disease (GD) [MIM:[http://omim.org/entry/230800 230800]]; also known as glucocerebrosidase deficiency.

== Publication Abstract from PubMed ==
 +
Gaucher disease, the most common lysosomal storage disease, is caused by mutations in the gene that encodes acid-beta-glucosidase (GlcCerase). Type 1 is characterized by hepatosplenomegaly, and types 2 and 3 by early or chronic onset of severe neurological symptoms. No clear correlation exists between the approximately 200 GlcCerase mutations and disease severity, although homozygosity for the common mutations N370S and L444P is associated with non- neuronopathic and neuronopathic disease, respectively. We report the X-ray structure of GlcCerase at 2.0 A resolution. The catalytic domain consists of a (beta/alpha)(8) TIM barrel, as expected for a member of the glucosidase hydrolase A clan. The distance between the catalytic residues E235 and E340 is consistent with a catalytic mechanism of retention. N370 is located on the longest alpha-helix (helix 7), which has several other mutations of residues that point into the TIM barrel. Helix 7 is at the interface between the TIM barrel and a separate immunoglobulin-like domain on which L444 is located, suggesting an important regulatory or structural role for this non-catalytic domain. The structure provides the possibility of engineering improved GlcCerase for enzyme-replacement therapy, and for designing structure-based drugs aimed at restoring the activity of defective GlcCerase.
