Fabry Disease

Fabry disease is a rare genetic disorder that affects many parts of the body. Understanding this condition is essential for those who might be affected or know someone who is.

What is Fabry Disease?

Fabry disease is a genetic disorder caused by a deficiency in the enzyme alpha-galactosidase A. This enzyme is crucial for breaking down a certain type of fat in the body. When it doesn't function correctly, fat builds up in the walls of blood vessels and other tissues, leading to various health problems.

Types of Fabry Disease

Classic Fabry Disease

Classic Fabry disease typically presents in childhood or adolescence. Symptoms tend to be severe and progress quickly if not treated.

Late-Onset Fabry Disease

Late-onset Fabry disease appears later in life, often with milder symptoms. It might not be diagnosed until adulthood because the symptoms develop more slowly.

Symptoms of Fabry Disease

Early Symptoms

Early signs of Fabry disease can include:

Advanced Symptoms

As the disease progresses, more severe symptoms can develop, including:

---

Fabry Disease Inheritance

Genetic Transmission

Fabry disease is inherited in an X-linked manner, meaning the gene responsible for the disorder is located on the X chromosome. Since males have only one X chromosome, they are more severely affected. Females have two X chromosomes, so they may be carriers and experience milder symptoms.

Family History and Genetic Counseling

If there is a family history of Fabry disease, genetic counseling can help. Genetic counselors can provide information about the risks of passing the disease to children and discuss testing options.

Diagnosing Fabry Disease

Initial Assessment

Doctors may suspect Fabry disease based on symptoms and family history. They will perform a physical examination and ask about the patient's medical history.

Diagnostic Tests

Several tests can confirm a Fabry disease diagnosis:

---

Treatment Options for Fabry Disease

Enzyme Replacement Therapy (ERT)

ERT involves regular infusions of a synthetic version of the alpha-galactosidase A enzyme. This treatment helps reduce the buildup of fat in the body and alleviate symptoms.

Chaperone Therapy

Chaperone therapy uses small molecules to stabilize the defective enzyme and enhance its function. This treatment is suitable for certain types of genetic mutations.

Gene Therapy

Gene therapy is an experimental approach that aims to correct the underlying genetic defect. Researchers are actively studying this promising treatment.

Symptom Management

Managing symptoms is essential for improving the quality of life for those with Fabry disease. This can include:

---

Preventing Fabry Disease

Genetic Counseling

Genetic counseling can help families understand their risks and make informed decisions about having children. It can also provide information about available prenatal testing options.

Prenatal Testing

Prenatal testing can identify Fabry disease in a fetus. Options include:

Living with Fabry Disease

Regular Monitoring

Regular check-ups with healthcare providers are crucial for managing Fabry disease. Monitoring kidney and heart function, as well as other affected organs, can help catch complications early.

Support Systems

Support groups and counseling can provide emotional support for individuals and families affected by Fabry disease. Connecting with others who understand the challenges can be incredibly beneficial.
