Qu'est-ce que la maladie de Fabry ?
[wp_show_posts id=”26245″]
**Q: What is Fabry Disease?**
**A:** Fabry disease, also known as Anderson-Fabry disease, is a rare genetic disorder characterized by the deficiency of an enzyme called alpha-galactosidase A (α-Gal A). This enzyme is responsible for breaking down a specific type of molecule called globotriaosylceramide (Gb3).
**Q: Causes of Fabry Disease**
**A:** Fabry disease is caused by mutations in the GLA gene, which encodes the α-Gal A enzyme. These mutations result in either a complete lack of enzyme activity or a reduction in its efficiency.
**Q: Types of Fabry Disease**
**A:** Fabry disease has two primary types:
* **Classical Fabry disease:** The most common and severe form, affecting males more severely.
* **Late-onset Fabry disease:** A less severe form that usually presents in males at a later age and females of all ages.
**Q: Symptoms of Fabry Disease**
**A:** Symptoms of Fabry disease can vary depending on the type and severity. Classical Fabry disease typically manifests in males during childhood or adolescence, while late-onset Fabry disease may present later in life. Common symptoms include:
* Burning or tingling pain in the hands and feet (acroparesthesias)
* Skin rashes
* Corneal clouding (whorls or opacities)
* Heart disease (cardiomyopathy, arrhythmias)
* Kidney disease
* Stroke
**Q: Diagnosis of Fabry Disease**
**A:** Fabry disease is diagnosed through a combination of clinical symptoms, family history, and enzyme activity testing. Genetic testing can also confirm the diagnosis.
**Q: Treatment for Fabry Disease**
**A:** There is no cure for Fabry disease, but treatments can effectively manage the symptoms and prevent or slow down complications. Treatment options include:
* Enzyme replacement therapy (ERT): Injections of synthetic α-Gal A enzyme.
* Chaperone therapy: Medications that help stabilize the enzyme and improve its activity.
* Dialysis and kidney transplantation: For severe kidney disease.
* Medications to manage specific symptoms, such as pain, heart conditions, and kidney dysfunction.
**Q: Prognosis for Fabry Disease**
**A:** With early diagnosis and treatment, the prognosis for Fabry disease can be improved. Disease progression and life expectancy vary depending on the type and severity of the condition. However, regular monitoring and disease management are crucial for maintaining a good quality of life.
**Q: Importance of Awareness and Screening**
**A:** Fabry disease is a rare but treatable condition. Raising awareness and increasing screening efforts can lead to early diagnosis and improved outcomes. Individuals with Fabry disease or those with a family history should seek medical evaluation to determine if they have the condition.
