Fabry disease is a type of lysosomal storage disease. Lysosomes are round structures found in the cells of the body that are full of special proteins called enzymes. Lysosomal enzymes help breakdown other proteins, carbohydrates, fats, and other substances. In Fabry disease, there is not enough of the enzyme alpha-galactosidase (alpha-GAL). Alpha-GAL helps breakdown a fatty acid called "globotriaosylceramide" or GL3 ". Without enough alpha-GAL, the lysosomes become filled with GL-3 and can not work well. Symptoms of Fabry disease may include episodes of pain, especially in the hands and feet, 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. Internal organs, such as the kidney, heart or brain, may also be affected, leading to progressive kidney damage, heart attacks, and strokes. Milder forms of Fabry disease may appear later in life and affect only the heart or kidneys. Fabry disease is caused by certain changes (pathogenic variants, also called genetic changes) in the GLA gene. Since the GLA gene is located on the X chromosome, Fabry disease is inherited in an X-linked manner. Although an enzyme assay test measuring the activity of alpha-GAL can diagnose Fabry disease in males, diagnosis is usually made by genetic testing in both males and females.

About Fabry disease
Many rare diseases have limited information. Currently, GARD aims to provide the following information for this disease:
Population Estimate:Fewer than 5,000 people in the U.S. have thisdisease.
Symptoms:May start to appear from Childhood to Adulthood.
Cause:This disease is caused by a genetic change that prevents lysosomes from properly removing toxins.
Organizations:Patient organizations are available to help find a specialist, or advocacy and support for this specific disease.
Newborn Screening:This disease may be detected through newborn screening tests performed soon afterbirth.
Symptoms of this disease may start to appear from Childhood to Adulthood.
The age symptoms may begin to appear differs between diseases. Symptoms may begin in a single age range, or during several age ranges. The symptoms of some diseases may begin at any age. Knowing when symptoms may have appeared can help medical providers find the correct diagnosis.

What Causes This Disease?
Genetic Mutations
Fabry disease is caused by genetic mutations, also known as pathogenic variants. Genetic mutations can be hereditary, when parents pass them down to their children, or they may occur randomly when cells are dividing. Genetic mutations may also result from contracted viruses, environmental factors, such as UV radiation from sunlight exposure, or a combination of any of these. Learn more about genetic diseases from the National Library of Medicine (NLM).
If you suspect you may have this disease, you may want to start collecting your family health history. Information such as other family members who have had similar symptoms, when their/your symptoms first appeared, or exposures to any potential disease-causing environmental factors should be discussed with your medical team. This tool from the Surgeon General can help you collect your family health history.
Can This Disease Be Passed Down From Parent to Child?
Yes. It is possible for a biological parent to pass down genetic mutations that cause or increase the chances of getting this disease to their child. This is known as inheritance. Knowing whether other family members have previously had this disease, also known as family health history, can be very important information for your medical team. This tool from the Surgeon General can help you collect your family health history.
There are multiple ways, or patterns, a disease can be inherited depending on the gene(s) involved. Based on GARD's current data, this disease can be inherited in the following pattern(s):
X-Linked
X-linked inheritance means the genetic mutation is located on the X chromosome, one of the sex chromosomes. The male sex chromosome pair consists of one X and one Y chromosome (XY). The female sex chromosome pair consists of two X chromosomes (XX). Because males have just one X chromosome, it takes only one copy of the mutated gene to cause the disease. Females that have one copy of the mutated gene may have symptoms similar to those experienced by affected males, but usually have less severe symptoms, or no symptoms at all.
Female parents with one X-linked mutated gene have a 50% chance of passing on the mutation to each of their biological children. Male parents with an X-linked mutated gene will pass on the mutation to all their female children but cannot pass the mutation on to their male children.
Patient organizations can help patients and families connect. They build public awareness of the disease and are a driving force behind research to improve patients' lives. They may offer online and in-person resources to help people live well with their disease. Many collaborate with medical experts and researchers.
Services of patient organizations differ, but may include:
Ways to connect to others and share personal stories
Easy-to-read information
Up-to-date treatment and research information
Patient registries
Lists of specialists or specialty centers
Financial aid and travel resources

Clinical studies are part of clinical research and play an important role in medical advances, including for rare diseases. Through clinical studies, researchers may ultimately uncover better ways to treat, prevent, diagnose, and understand human diseases.
What Are Clinical Studies?
Clinical studies are medical research involving people as participants. There are two main types of clinical studies:
Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments.
Observational studies involve recording changes over time among a specific group of people in their natural settings.
People participate in clinical trials for many reasons. People with a disease may participate to receive the newest possible treatment and additional care from clinical study staff as well as to help others living with the same or similar disease. Healthy volunteers may participate to help others and to contribute to moving science forward.
To find the right clinical study we recommend you consult your doctors, other trusted medical professionals, and patient organizations. Additionally, you can use ClinicalTrials.gov to search for clinical studies by disease, terms, or location.
What if There Are No Available Clinical Studies?
ResearchMatch helps connect people interested in research studies with researchers from top medical centers across the United States. Anyone from the U.S. can register with this free program funded by NIH. Researchers from participating institutions use the database to search for and invite patients or healthy volunteers who meet their study criteria to participate.
Join the All of Us Research Program!
The All of Us Research Program is inviting 1 million people from all backgrounds across the U.S. to help build one of the most diverse health databases in history. Researchers will use the data to learn how our biology, lifestyle, and environment affect health. This may one day help them find ways to treat and prevent diseases.
