What is genetic counselling?
Genetic counselling is the process of getting information from qualified professionals about the genetic condition or conditions that affect your family.
If you have a genetic condition in your family, genetic counselling can help you learn about:
- how the condition might progress
- how your family life might change because of the condition
- how likely it is that other family members will get the condition
- how you can manage the condition in your family.
People often get genetic counselling before or at the same time as genetic testing. Genetic testing is medical tests for people who have symptoms or a family history of a genetic condition. Genetic testing can tell you how likely it is that you might pass a genetic condition on to a child.
What is a genetic condition?
A genetic condition is a condition caused by changes in genes. A change or mistake in just one gene can cause a serious medical condition or disability. Sometimes one or both parents pass on changed or abnormal genes to their child. Other times changes happen in a baby’s genes at or during conception.
Aims of genetic counselling
If you have a child with a genetic condition, genetic counselling can help you and your family understand the diagnosis and adjust to it.
You might want genetic counselling so you can:
- understand the medical facts about your child’s condition – including the diagnosis, the likely cause of the condition and the options for managing it
- understand whether you or your child’s other parent passed on genetic changes to your child
- learn more about what the risk is, and how to deal with it if you have more children
- plan realistically for the future
- adjust in the most positive ways to the condition or to the risk of the condition in another family member.
Some people also seek counselling to confirm what they’ve learned online. Others want help thinking about decisions they need to make, or support for decisions they’ve already made.
Many people find that genetic counselling is very helpful and informative.
When to seek genetic counselling
Genetic counselling can help when:
- a condition seems to run in the family and there’s concern that you or your children might develop it
- a child in the family has a serious problem that affects growth, development or health, possibly linked with a genetic cause
- two people who are closely related are thinking of having a child together
- prenatal testing has detected a fetal abnormality or a risk of a fetal abnormality
- there’s concern about exposure to some chemical or environmental agent during pregnancy that might cause birth defects.
You might also be referred for genetic counselling as part of a diagnosis or to manage a genetic condition.
Preparing for genetic counselling
Before you go to a genetic counselling session, it’s a good idea to find out as much as you can about your family’s medical history, because you’ll be asked to give the counsellor detailed information.
This might include:
- your relation to each family member, including whether family members are adopted or half-relatives
- any major health conditions that affect each family member and any relevant pregnancy history like miscarriage
- the age of onset of each condition
- the cause and age of death of family members (if relevant).
What to expect at a genetic counselling session
During a genetic counselling session, you’ll speak to a genetic counsellor. The counsellor might:
- ask for your family history
- make or confirm a diagnosis, or let you know there’s no genetic condition present
- work out the risk of other family members getting the condition you’re concerned about
- talk about how the condition will affect your child, and how you might handle this
- send you to support agencies or other medical professionals
- give you verbal and written information about the condition.
The counsellor might also organise further testing if you need it.
After a counselling session, you should expect to:
- know more about the condition and/or genetic tests that you’re interested in
- feel supported because the counsellor has listened to you, understood your concerns, and encouraged you
- have thought about how to handle the situation as a family – sessions are designed to help the whole family
- have the information and support you need to make your own decisions about genetic conditions and/or treatments
- know where to go for information and support for decision-making, complications and emotional ups and downs in the future.
Following up after a counselling session
Genetic counsellors don’t make decisions for you. Their role is to give you relevant and accurate information, help you think about the options, and support you as you make decisions.
These decisions might include:
- whether to have genetic testing done
- who to tell about the results of the test
- whether you want medical treatment (if it’s available)
- how you’re going to live your life in response to the results of the testing
- how much support you’re going to need.
