Fabry is a rare disease caused by changes in the GLA gene, which may be referred to as mutations or variants.
People with Fabry disease have trouble breaking down and getting rid of certain fatty waste substances (substrates) in cells. This happens because of a variant in the GLA gene that leads to a defective or absent enzyme called alpha-Gal A. When alpha-Gal A is present and functioning, it travels to the cell’s recycling center, called the lysosome, to break down the fatty substances in the cell.
In Fabry disease, without fully functioning alpha-Gal A, the fatty substances build up in the body, causing damage to tissues and organs.
Fabry disease can affect many parts of the body, including the kidneys, heart, nervous system, skin, eyes, and others. For this reason, many different healthcare providers may be involved in treating and monitoring people with Fabry disease.
Because Fabry disease has a wide range of symptoms, every person's experience with Fabry may be unique. It can cause many types of health issues that may get worse at different rates in different people and may ultimately affect lifespan.
“Any time I was at the beach or on the golf course, I had pain in my hands and feet that wouldn’t go away—no matter the medicine I took. However, I soon discovered that the pain seemed to be associated with heat and went away if I held something cold or went into the water.”

Each of us has information (called DNA) coded in our cells. We inherit this DNA from our parents. Fabry disease can be passed down by either parent. This is because the GLA variant is found on the X chromosome.
A father with Fabry disease passes along his mutation to all of his daughters. This is because daughters get their father’s only X chromosome with the mutated GLA variant. A father with Fabry disease never passes the GLA variant to his sons, because sons get a Y chromosome from their fathers.
A mother who has the GLA variant on one of her 2 X chromosomes has a 50% chance of passing down Fabry disease to each of her children (male or female). Because men only have 1 X chromosome, if they inherit the variant, they will all develop Fabry disease. In affected females, the GLA gene may work normally in some parts of the body but not others. This is believed to be one reason why females have more variable symptoms than males.
In rare cases, Fabry may not be inherited. Mutations may spontaneously occur and be unique to the individual. These are known as de novo mutations. However, these individuals may still be able to pass the disease on to their children.

“In the early stages of being diagnosed with the disease, doctors acted like I didn’t have any symptoms because I was a woman. Talk about frustrating! Contrary to popular belief, women and girls can have severe Fabry symptoms. I am one of them.”

Fabry disease is not caused by one single genetic variant. In fact, there are numerous GLA variants that can cause the disease. GLA variants are written as letters and numbers such as c.155G>A, p.C52Y, which refers to the location of the variant on the GLA gene in a patient. These different GLA variants can cause different types of problems in people with Fabry disease.
A diagnosis may be confirmed through laboratory testing.
There are two types of tests:

What is Galafold?
Galafold is a prescription medicine used to treat adults with Fabry disease who have a certain genetic change (variant) in the galactosidase alpha gene (GLA) that is responsive (amenable) to Galafold.
It is not known if Galafold is safe and effective in children.
