Why You Should Consider Genetic Carrier Screening in Pregnancy??

Dr. Keith Figueiredo

Pregnancy is an exciting journey, but it’s also a time to think about your baby’s health. Did you know that every pregnancy has a small chance of resulting in a baby with a serious genetic condition? While the risk is low—around 1 to 2 per 100 children—it’s worth being informed about your options to minimize surprises.

Understanding Genetic Conditions

In Australia, about 1 in 20 people carry the gene for one of these three common genetic conditions, and 1 in 160 couples will be found to be at risk of having an affected child:

Cystic Fibrosis (CF)

A severe condition causing lung and digestive problems, affecting 1 in 2,500 people.

Spinal Muscular Atrophy (SMA)

A neuromuscular disease affecting 1 in 6,000 people, historically associated with high morbidity.

Fragile X Syndrome (FXS)

The most common inherited cause of intellectual disability, affecting 1 in 3,600 men and 1 in 6,000 women.

What Does Being a Carrier Mean?

Being a carrier of a genetic condition usually does not affect your health, and most people identified as carriers have no family history of the condition.

Key Fact

Even if you have no known genetic conditions in your family, you could still be a carrier.

Did You Know?

The number of pregnancies affected by CF, SMA, or FXS is comparable to the number of live births affected by Down syndrome

Why Get Carrier Screening?

Genetic carrier screening offers several benefits:

Peace of Mind: A low-risk result can reassure you.
Preparation: If you’re identified as a carrier, you can plan for your baby’s future.
Informed Choices: Knowing your risk helps you make the best decisions for your family.

Who Should Get Tested?

Australian clinical guidelines recommend genetic carrier screening for:

Women or couples planning a pregnancy.
Couples in the early stages of pregnancy.

How Does Genetic Carrier Screening Work?

The test is a simple blood test that screens for CF, SMA, and FXS.
Eligible individuals can access this test once in a lifetime through Medicare (bulk-billed if eligible).

Why Get Carrier Screening?

Carrier screening is optional, but it’s helpful to reflect on these questions:

Do I want to know my risk of having a child with a genetic condition?
How would I feel about the results?
What steps would I take if my risk were higher than expected?

What If I’m a Carrier?

If the screening shows you’re a carrier:

Your doctor will recommend testing your partner.
If both partners are carriers, genetic counselling is available to discuss next steps.
You can then explore options like IVF with genetic testing or prenatal diagnosis if you wish.
