Once you have worked out which relatives may be at risk of Fabry, you can decide when and how you might want to talk to them.
It doesn’t matter how you choose to communicate with them. Face-to-face, over the phone, online, or via email – there is no correct way. However, there are some important points you may want to cover:
All of the above points are covered in the "Your family and Fabry" pamphlet, which is available to download. Also available in the resource section is an example letter if you want to write to your relatives but can’t find the right words – you can send it as it is or use it to help you write your own.
If they want to know more, they can go and speak to a healthcare professional about their potential risk of Fabry
If your family members would like to find out more about Fabry, or be tested, the next step for them is to go and see a healthcare professional. Depending on the individual situation this might be:
Speaking to a healthcare professional
Your family members can have a discussion with a healthcare professional, who will likely assess their potential risk of having Fabry, explain the nature of the genetic tests including potential advantages and disadvantages, and arrange for a test if it is appropriate and should they wish it.
Getting tested
Genetic tests are usually performed on a cheek swab, blood, or other tissue sample.11 Tests will be performed to look for mutations associated with Fabry. 3
If a Fabry mutation is found
If a Fabry mutation is found, their medical team will tell them more about the disease, how to manage it, and any potential implications.
If family members choose not to be tested
If family members choose not to be tested for Fabry disease, it’s important they let their healthcare team know that Fabry is in their family. If they have any Fabry-related health issues, this could prompt a diagnosis.
