Fabry disease is an X-linked lysosomal disorder caused by a faulty gene. Because of this error an essential enzyme known as alpha galactosidase, is either missing or is present in insufficient amounts.
Without this enzyme, certain substances primarily one called globotriaosylceramide, or GL-3 are not removed from the body, and builds up in the cells. It is this progressive build-up of materials that cause most of the problems in Fabry disease.
Characteristic features of Fabry disease include episodes of pain, particularly in the hands and feet (acroparesthesias); clusters of small, dark red spots on the skin called angiokeratomas; a decreased ability to sweat (hypohidrosis); cloudiness of the front part of the eye (corneal opacity); and hearing loss. Fabry disease also involves potentially life-threatening complications such as progressive kidney damage, heart attack, and stroke. Milder forms of the disorder may appear later in life and affect only the heart or kidneys.
How common is Fabry disease?
Fabry disease affects an estimated 1 in 40,000 males. This disorder also occurs in females, although less frequently. Milder, late-onset forms of the disorder are probably more common than the classic, severe form.
What other names do people use for Fabry disease?
- Alpha-galactosidase A deficiency
- Anderson–Fabry disease
- Angiokeratoma corporis diffusum
- Angiokeratoma diffuse
- Ceramide trihexosidase deficiency
- Fabry’s disease
- GLA deficiency
- Hereditary dystopic lipidosis
Treatments for Fabry disease
Enzyme replacement therapy is now available for Fabry disease. This treatment helps to reduce the storage of glycosphingolipids, ease pain, and improve organ function.
The Hide and Seek Foundation has a nice summary of Fabry disease.
