What it is
CarrierMap is a genetic carrier screen designed to help determine your risk of having a child with an inherited genetic disease.
WHO IT’S FOR
Carrier screening is recommended for people who are planning a family or early in pregnancy, even those without any family history of genetic disease.
In fact, 80% of children born with a genetic condition have no family history of that disease. Carrier screening is an easy way to find out if changes in your DNA make you more likely to have an affected child.
Carrier screening is appropriate for people who are:
- Thinking of having a child
- Trying to conceive (TTC)
- Undergoing fertility treatments or IVF
- Considering egg freezing
- Currently pregnant
How it works
The CarrierMap screen looks for mutations, or changes, in both you and your partner’s genes that together can increase your risk to have a child with genetic disease.
Genes provide instructions for the body to grow, function, and repair itself. Sometimes mutations in these genes, if inherited by your children, can cause genetic disease and can significantly impact their health and well-being.
Learning about your genes can help you make decisions about your family’s health. For each condition on the CarrierMap screen, you will be identified as either a carrier, indicating an increased risk, or a non-carrier, indicating a significantly decreased risk. Carriers usually do not have any symptoms and may not have any family history of the condition they carry, making screening important for everyone.
After CarrierMap Testing
Once your CarrierMap results are ready, they will be sent directly to your doctor.
After your CarrierMap screening results are in, they will be sent to your doctor, and you’ll have the opportunity to review them over the phone with a specially trained genetic counselor.
If you are found to have an increased risk of passing on a high-impact genetic disease, you have a number of reproductive options available to you:
- Preimplantation genetic diagnosis (PGD), which involves IVF and then genetic testing of embryos
- Using a sperm or egg donor who does not carry that genetic disease
- Testing the pregnancy via chorionic villus sampling (CVS) or amniocentesis
- Adopting a child
- Continuing with family planning and pregnancy
