" /> Gaucher disease, type I - CISMeF





Preferred Label : Gaucher disease, type I;

Symbol : GD1;

CISMeF acronym : GD1;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Gaucher disease, noncerebral juvenile; Glucocerebrosidase deficiency; Gba deficiency; Acid beta-glucosidase deficiency; Gd I;

Description : Gaucher disease is an autosomal recessive lysosomal storage disorder due to deficient activity of beta-glucocerebrosidase. As a result of this deficiency, there is intracellular accumulation of glucosylceramide (GlcCer, glucosylcerebroside) primarily within cells of mononuclear phagocyte origin, which are the characteristic 'Gaucher cells' identified in most tissues (Jmoudiak and Futerman, 2005). Gaucher disease is classically categorized phenotypically into 3 main subtypes: nonneuronopathic type I, acute neuronopathic type II (230900), and subacute neuronopathic type III (231000). Type I is the most common form of Gaucher disease and lacks primary central nervous system involvement. Types II and III have central nervous system involvement and neurologic manifestations (Knudson and Kaplan, 1962; Jmoudiak and Futerman, 2005). All 3 forms of Gaucher disease are caused by mutation in the GBA gene. There are 2 additional phenotypes which may be distinguished: perinatal lethal Gaucher disease (608013), which is a severe form of type II, and Gaucher disease type IIIC (231005), which also has cardiovascular calcifications. See also 610539 for a form of atypical Gaucher disease caused by mutation in the gene encoding saposin C (PSAP; 176801), which is an activator of beta-glucosidase.;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the acid beta glucosidase gene (GBA, 606463.0001);

Neoplasia : Increased risk for multiple myeloma; Increased risk for monoclonal gammopathy;

Laboratory abnormalities : Acid beta-glucosidase deficiency; Increased bone serum acid phosphatase;

Prefixed ID : #230800;
