Synonyms of Fucosidosis
- alpha-L-fucosidase deficiency
- fucosidosis type 1
- fucosidosis type 2
Fucosidosis is a rare genetic disorder characterized by deficiency of the enzyme alpha-L-fucosidase, which is required to break down (metabolize) certain complex compounds (e.g., fucose-containing glycolipids or fucose-containing glycoproteins). Fucose is a type of the sugar required by the body to perform certain functions (essential sugar). The inability to breakdown fucose-containing compounds results in their accumulation in various tissues in the body. Fucosidosis results in progressive neurological deterioration, skin abnormalities, growth retardation, skeletal disease and coarsening of facial features. The symptoms and severity of fucosidosis are highly variable and the disorder represents a disease spectrum in which individuals with mild cases have been known to live into the third or fourth decades. Individuals with severe cases of fucosidosis can develop life-threatening complications early in childhood.
The disorder belongs to a group of diseases known as lysosomal storage disorders. Lysosomes are particles bound in membranes within cells that function as the primary digestive units within cells. Enzymes within lysosomes break down or digest particular nutrients, such as certain fats and carbohydrates. Low levels or inactivity of the alpha-L-fucosidase enzyme leads to the abnormal accumulation of fucose-containing compounds in the tissues of individuals with fucosidosis.
