Fabry Disease: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 23, 2026.
What kind of doctor treats Fabry Disease?
A geneticist, a doctor who treats inherited conditions, often leads care for Fabry disease. Because it can harm the kidneys, heart, and brain, you may also see a nephrologist (a kidney doctor) and a cardiologist (a heart doctor). A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Fabry disease?
Fabry disease is an inherited disorder. A type of fat, called globotriaosylceramide, builds up in the body's cells. Beginning in childhood, this buildup causes signs and symptoms that affect many parts of the body.
It can also cause serious complications, such as kidney failure, heart failure, and stroke. Some people have milder forms that appear later in life. These forms usually involve only the heart, kidneys, or blood vessels in the brain.
Fabry disease is rare. It affects an estimated 1 in 1,000 to 9,000 people.
Symptoms
Common features include:
- Episodes of pain, especially in the hands and feet. The burning pain can get worse in hot weather or after exercise.
- Clusters of small, dark red spots on the skin, called angiokeratomas.
- A decreased ability to sweat.
- Cloudiness or streaks in the front part of the eye, called the cornea. The cloudiness does not change vision.
- Stomach and bowel problems.
- Ringing in the ears (tinnitus) and hearing loss.
Over time, the fat buildup can also lead to an enlarged heart, irregular heartbeats called arrhythmias, and kidney damage that can lead to kidney failure.
Women and girls can have symptoms too. Their symptoms usually begin later in life and are milder than in affected male relatives.
Causes and who gets it
Fabry disease is caused by changes, called variants, in the GLA gene. This gene gives instructions for making an enzyme, a protein that does a job in the body. The enzyme, alpha-galactosidase A, normally breaks down the fat. A gene change keeps it from doing this well, so the fat builds up.
The condition is X-linked. This means the changed gene is on the X chromosome, one of the two sex chromosomes. Males have one X chromosome, so one changed copy of the gene is enough to cause the condition.
Affected men pass the changed gene to all of their daughters and none of their sons. Sons of female carriers have a 50% chance of inheriting the gene and being affected.
How doctors diagnose it
Doctors should suspect Fabry disease in people who have more than one of its features. Examples are dark red skin spots, painful episodes in the hands and feet, or an unexplained stroke.
In males, the most reliable test measures how active the enzyme is in the blood. Low activity points to Fabry disease. A gene test can confirm it.
In females, doctors use a gene test, because the enzyme test is unreliable.
A genetic counselor can help explain the risks of passing it on.
Treatment
Care ideally involves a team of specialists in the areas the disease affects. Treatment includes the following.
- Enzyme replacement therapy (ERT) replaces the missing enzyme through a vein. The medicines include agalsidase alfa (Replagal), agalsidase beta (Fabrazyme), and pegunigalsidase alfa-iwxj (Elfabrio). They can reduce fat buildup, ease pain, and protect organ function in some people.
- Migalastat (Galafold) is a pill. The FDA has approved it for adults who have a certain gene change.
- Medicines can treat pain and stomach problems, but they do not treat the disease itself.
- Blood-thinning medicines called anti-platelet drugs can help prevent strokes. Blood pressure medicines can slow the decline of kidney function.
- Some people need a kidney transplant or dialysis, a treatment that cleans the blood when the kidneys fail.
Antibodies against the enzyme medicines have been reported in males. Experts say ERT may have a limited effect on long-term outcomes. They still advise starting it early in males with Fabry disease.
When to see a doctor
Call 911 or go to the emergency room if you have chest pain or discomfort lasting for two minutes or more, trouble breathing, fainting, or sudden dizziness, weakness, or change in vision. Fabry disease can lead to heart failure and stroke.
See a doctor if you or your child has burning pain in the hands and feet, dark red spots on the skin, or a lower ability to sweat. Also talk to a doctor if Fabry disease runs in your family.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can do an evaluation, order first tests, and follow your health over time. They can also coordinate care with a geneticist, kidney doctor, and heart doctor.
Common questions
Is Fabry disease inherited?
Yes. Fabry disease is inherited in an X-linked pattern, which means the changed GLA gene is on the X chromosome. Affected men pass the changed gene to all of their daughters and none of their sons.
Does Fabry disease only affect males?
No. Females can have it too. Unlike other X-linked disorders, Fabry disease causes significant medical problems in many females who have one changed copy of the gene. Their symptoms usually begin later in life and are milder.
Is there treatment for Fabry disease?
Yes. Enzyme replacement therapy is given through a vein. An oral medicine called migalastat is approved for adults who have a certain gene change. Other medicines help with pain and protect the kidneys and brain.
