GD is the most prevalent lysosomal storage disease, characterized by accumulation of glucosylceramide in the reticulo-endothelial system. Different clinical forms are recognized depending on the presence (neuronopathic forms) or absence of central nervous system involvement, severity and age of onset.<ref>PMID:8294033</ref> [:]<ref>PMID:19286695</ref> <ref>PMID:16293621</ref> <ref>PMID:1974409</ref> <ref>PMID:1972019</ref> <ref>PMID:8432537</ref> <ref>PMID:7916532</ref> <ref>PMID:8112750</ref> <ref>PMID:8076951</ref> <ref>PMID:8790604</ref> <ref>PMID:7627184</ref> <ref>PMID:7627192</ref> <ref>PMID:8937765</ref> <ref>PMID:8829654</ref> <ref>PMID:8829663</ref> <ref>PMID:8889591</ref> <ref>PMID:8780099</ref> <ref>PMID:9182788</ref> <ref>PMID:9217217</ref> <ref>PMID:9279145</ref> <ref>PMID:9153297</ref> <ref>PMID:9061570</ref> <ref>PMID:9554454</ref> <ref>PMID:9683600</ref> <ref>PMID:9637431</ref> <ref>PMID:9516376</ref> <ref>PMID:9851895</ref> <ref>PMID:9650766</ref> <ref>PMID:9554746</ref> <ref>PMID:10206680</ref> <ref>PMID:10340647</ref> <ref>PMID:10360404</ref> <ref>PMID:10744424</ref> <ref>PMID:10352942</ref> <ref>PMID:10447266</ref> <ref>PMID:10796875</ref> <ref>PMID:11992489</ref> <ref>PMID:11933202</ref> <ref>PMID:12204005</ref> <ref>PMID:12847165</ref> <ref>PMID:15292921</ref> <ref>PMID:15826241</ref> <ref>PMID:15605411</ref> <ref>PMID:16148263</ref> <ref>PMID:17620502</ref> <ref>PMID:18332251</ref> <ref>PMID:19846850</ref>   Defects in GBA are the cause of Gaucher disease type 1 (GD1) [MIM:[https://omim.org/entry/230800 230800]; also known as adult non-neuronopathic Gaucher disease.

It is a distinct form of Gaucher disease type 2, characterized by fetal onset. Hydrops fetalis, in utero fetal death and neonatal distress are prominent features. When hydrops is absent, neurologic involvement begins in the first week and leads to death within 3 months. Hepatosplenomegaly is a major sign, and is associated with ichthyosis, arthrogryposis, and facial dysmorphism.<ref>PMID:19286695</ref> <ref>PMID:12847165</ref> <ref>PMID:16148263</ref> <ref>PMID:17620502</ref> <ref>PMID:18332251</ref> <ref>PMID:19846850</ref>   Note=Perinatal lethal Gaucher disease is associated with non-immune hydrops fetalis, a generalized edema of the fetus with fluid accumulation in the body cavities due to non-immune causes. Non-immune hydrops fetalis is not a diagnosis in itself but a symptom, a feature of many genetic disorders, and the end-stage of a wide variety of disorders.<ref>PMID:19286695</ref> <ref>PMID:12847165</ref> <ref>PMID:16148263</ref> <ref>PMID:17620502</ref> <ref>PMID:18332251</ref> <ref>PMID:19846850</ref>   Defects in GBA contribute to susceptibility to Parkinson disease (PARK) [MIM:[https://omim.org/entry/168600 168600]. A complex neurodegenerative disorder characterized by bradykinesia, resting tremor, muscular rigidity and postural instability. Additional features are characteristic postural abnormalities, dysautonomia, dystonic cramps, and dementia. The pathology of Parkinson disease involves the loss of dopaminergic neurons in the substantia nigra and the presence of Lewy bodies (intraneuronal accumulations of aggregated proteins), in surviving neurons in various areas of the brain. The disease is progressive and usually manifests after the age of 50 years, although early-onset cases (before 50 years) are known. The majority of the cases are sporadic suggesting a multifactorial etiology based on environmental and genetic factors. However, some patients present with a positive family history for the disease. Familial forms of the disease usually begin at earlier ages and are associated with atypical clinical features.<ref>PMID:19286695</ref> <ref>PMID:12847165</ref> <ref>PMID:16148263</ref> <ref>PMID:17620502</ref> <ref>PMID:18332251</ref> <ref>PMID:19846850</ref>

-== Publication Abstract from PubMed ==
-The lysosomal glycoside hydrolase beta-glucocerebrosidase (GBA; sometimes called GBA1 or GCase) catalyses the hydrolysis of glycosphingolipids. Inherited deficiencies in GBA cause the lysosomal storage disorder Gaucher disease (GD). Consequently, GBA is of considerable medical interest, with continuous advances in the development of inhibitors, chaperones and activity-based probes. The development of new GBA inhibitors requires a source of active protein; however, the majority of structural and mechanistic studies of GBA today rely on clinical enzyme-replacement therapy (ERT) formulations, which are incredibly costly and are often difficult to obtain in adequate supply. Here, the production of active crystallizable GBA in insect cells using a baculovirus expression system is reported, providing a nonclinical source of recombinant GBA with comparable activity and biophysical properties to ERT preparations. Furthermore, a novel crystal form of GBA is described which diffracts to give a 0.98 A resolution unliganded structure. A structure in complex with the inactivator 2,4-dinitrophenyl-2-deoxy-2-fluoro-beta-D-glucopyranoside was also obtained, demonstrating the ability of this GBA formulation to be used in ligand-binding studies. In light of its purity, stability and activity, the GBA production protocol described here should circumvent the need for ERT formulations for structural and biochemical studies and serve to support GD research.
