" /> Fabry disease - CISMeF





Preferred Label : Fabry disease;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Angiokeratoma corporis diffusum; Anderson-fabry disease; Hereditary dystopic lipidosis; Alpha-galactosidase a deficiency; Gla deficiency; Ceramide trihexosidase deficiency;

Included titles and symbols : Fabry disease, cardiac variant;

Description : Fabry disease is an X-linked inborn error of glycosphingolipid catabolism resulting from deficient or absent activity of the lysosomal enzyme alpha-galactosidase A. This enzymatic defect leads to the systemic accumulation of globotriaoslyceramide (Gb3) and related glycosphingolipids in the plasma and cellular lysosomes of vessels, nerves, tissues, and organs throughout the body (Nance et al., 2006). The disorder is a systemic disease, manifest as progressive renal failure, cardiac disease, cerebrovascular disease, small-fiber peripheral neuropathy, and skin lesions, among other abnormalities (Schiffmann, 2009). An atypical variant of Fabry disease has been reported in which cardiac disease, specifically left ventricular hypertrophy, with or without renal failure, develops in the sixth decade of life. These patients have residual GLA activity (Nakao et al., 1995; Nakao et al., 2003). Although previously considered an X-linked recessive disorder, Wang et al. (2007) found that heterozygous women with Fabry disease experience significant life-threatening conditions requiring medical treatment and intervention. Thus, heterozygous Fabry women should not be called carriers, as this term underestimates the seriousness of the disease in these patients. Clarke (2007) and Schiffmann (2009) provided detailed reviews of Fabry disease.;

Inheritance : X-linked;

Molecular basis : Caused by mutation in alpha-galactosidase A gene (GLA, 300644.0001);

Laboratory abnormalities : Proteinuria; Increased plasma globotriaosylsphingosine (lyso-GB3); Increased level of globotriaosylceramide (GB3) in plasma and urinary sediment; Intracellular glycosphingolipid deposition in all tissues of the body; Alpha-galactosidase A deficiency in plasma, leukocytes, or fibroblasts;

Prefixed ID : #301500;
