Carrier screening for genetic diseases
Even without a family history of genetic disease, it is possible to carry a serious genetic disease and be at risk of having a child with the disease. Individuals who are carriers usually have no symptoms.
Carrier screening allows prospective parents to identify the potential risks of genetic diseases in their children, such as cystic fibrosis, spinal muscular atrophy or Tay-Sachs disease. This genetic test performed before or during pregnancy can be customized according to the concerns of the couple and can analyze up to 301 genes.
When a couple is identified to be at risk, our genetic counsellor discusses in detail the risks, the disease and if treatment is available, as well as the reproductive options.

Each of us carries at least one genetic disease. Even though we have no symptoms or family history of this disease, we can still have a modified copy of this gene. When both parents carry a mutation in the same gene, their children have a 25% risk of having the disease, regardless of gender. This is called autosomal recessive inheritance.
Other diseases are transmitted by a carrier mother (X-linked transmission) and usually affect their sons.
Genetic screening can cover several genetic diseases, including:
Spinal muscular atrophy
Fragile X syndrome
Duchenne muscular dystrophy
Up to 300 genetic diseases
