Diseases & Conditions

Fabry's Disease

What is Fabry Disease?

Fabry disease is caused by the lack of or faulty enzyme needed to metabolize lipids, fat-like substances that include oils, waxes, and fatty acids. The disease is also called alpha-galactosidase-A deficiency. A mutation in the gene that controls this enzyme causes insufficient breakdown of lipids, which build up to harmful levels in the eyes, kidneys, autonomic nervous system, and cardiovascular system. Fabry disease is one of several lipid storage disorders and the only X-linked lipid storage disease. Since the gene that is altered is carried on a mother’s X chromosome, her sons have a 50 percent chance of inheriting the disorder and her daughters have a 50 percent chance of being a carrier. A milder form is common in females, and occasionally some affected females may have severe manifestations similar to males with the disorder. Symptoms usually begin during childhood or adolescence and include burning sensations in the hands that gets worse with exercise and hot weather and small, non-cancerous, raised reddish-purple blemishes on the skin. Some boys will also have eye manifestations, especially cloudiness of the cornea. Lipid storage may lead to impaired arterial circulation and increased risk of heart attack or stroke. The heart may also become enlarged and the kidneys may become progressively involved. Other signs include decreased sweating, fever, and gastrointestinal difficulties.

Is there any treatment?

Enzyme replacement therapy has been approved by the U.S. Food and Drug Administration for the treatment of Fabry disease. Enzyme replacement therapy can reduce lipid storage, ease pain, and improve organ function. The pain that accompanies the disease may be treated with anticonvulsants such as phenytoin and carbamazepine. Gastrointestinal hyperactivity may be treated with metoclopramide. Some individuals may require dialysis or kidney transplantation.

What is the prognosis?

Patients with Fabry disease often die prematurely of complications from strokes, heart disease, or renal failure.

What research is being done?

The National Institute of Neurological Disorders and Stroke (NINDS), a component of the National Institutes of Health, supports research to find ways to treat and prevent lipid storage diseases such as Fabry disease.
