In what cases is it indicated?

We all have alterations in our genes, and with the CGT we can find out if these alterations could lead to our children having a genetic disease. The test is recommended in the following cases.

• Prior to an assisted reproduction treatment: it is advised in order to know the risk of transmission so that the best type of treatment can be decided on in each case.
• Prior to a treatment using donor eggs or semen:in order to be able to select a donor who is not a carrier of the same mutation as the member of the couple who is providing the gametes (ova or spermatozoa) we carry out the test on our donors.
• Before trying to become pregnant naturally:for any woman who wants to become pregnant, so that she knows the risk of passing on possible diseases to her child.

How is it done?

The test is carried out on DNA obtained from blood samples from the father and the mother. The results come through in a month, and we can then find out the probability of your child suffering from a genetic disease.

What happens when a mutation is detected?

When a mutation is detected in one member of a couple, nothing is done unless the other member of the couple has a mutation in the same gene. This would result in there being a high risk of having children who suffer from the genetic disease.

In that case, the options for conceiving a child who is not affected by the disease are:

• Treatment with in vitro fertilisation and Pre-implantation Genetic Diagnosis: for the majority of these diseases, we can use this technique to determine which embryos are affected and implant in the mother only those that are free of the disease.
• Gamete donation: we can opt for an assisted reproduction treatment using sperm or eggs from a donor who is not a carrier of the disease.
