Fast Fabry facts

  • Fabry is a genetic condition that can be passed down the generations of a family1
  • The seriousness of Fabry varies, some people experience no symptoms while others develop life-threatening complications1
  • Fabry can affect most parts of the body creating a wide variety of symptoms1,2
  • Even people in the same family can have different symptom types and severities, as well as be different ages when the symptoms start3-6
  • Fabry is a rare disease – many people won’t have heard of it7
  • Fabry can be difficult to diagnose based on the symptoms alone1,8,9
  • You can check for Fabry using a genetic test, usually on a cheek swab, blood or other tissue sample6,10
  • There are different treatment options available for those with Fabry2,11
  • Fabry is progressive, it can get worse over time – early diagnosis and treatment could potentially lead to a healthier future1,2,11,12

What causes Fabry?

Fabry is caused by genetic mutations – they are usually passed on from parent to child, but in rare cases they can be unique to the individual.1,2

What is a mutation?3,4

Every cell of your body is programmed to work in a particular way, for example to help with digestion, keep your heart beating, or fight infections. To do its job properly, every single cell needs a set of instructions.

DNA is ‘read’ by the cell and provides these instructions. A gene is a section of DNA that programmes one specific instruction. The genes themselves are grouped into separate units called chromosomes.

You can think of this like an instruction manual where:

Sometimes there are changes in the DNA – these are called mutations (variants). You can think of these like misspelt words – one wrong letter can completely change the meaning of the word.

How do genetic mutations lead to Fabry?1,5

Fabry is caused by a variety of mutations in a gene called GLA which provides the instructions to make an enzyme (a-galactosidase A).

Normally this enzyme helps break down certain sugary-fatty substances (glycosphingolipids) in the cells of our body – but the mutations mean it can’t do its job. This leads to a build-up of those substances causing the symptoms of Fabry.

Families share genetics, meaning they can share Fabry mutations, click here to learn more

Is Fabry always inherited?2,5

Fabry and its mutations are most often inherited from a parent. In rare cases it may not be inherited, the Fabry mutations may spontaneously occur and be unique to the individual – these are known as de novo mutations. However, this individual may still be able to pass the disease onto their children.
