What do we mean by inherited or genetic disease?

In medicine, “genetic” or “inherited” mean conditions that are caused primarily by changes to DNA. It might mean that a change in a single gene is enough to cause the disease. Or, a change in a person’s chromosomes, or the packages of DNA inside cells, can cause problems with development.

If you aren't sure, feel welcome to tell us and we will have our genetics experts review the information. If you run out of room, there is a space at the end of your questionnaire to provide us with any additional information. Please include:

‚Äč

  • the name of the condition

  • who in the family has it and how they are related to you

  • how old they were when they first had symptoms or were diagnosed

  • their current age or the age when they passed away if they are no longer living
