Genetic compatibility testing, also called genetic matching, is a study to see what information about recessive diseases are carried in our genes and can be passed on to future children. These diseases are rare, but in many cases they are serious and incurable, such as spinal muscular atrophy, cystic fibrosis or autosomal recessive deafness.
HOW ARE RECESSIVE DISEASES PASSED ON TO DESCENDANTS?
We all carry recessive diseases in our genes, even if we are healthy people. Genetic compatibility testing helps us to detect them. We do not necessarily develop the disease, but we will pass these genes on to our descendants, who will have a 25% chance of developing the disease.
For the recessive disease to manifest itself, you need to inherit an altered copy from each biological parent. When the mutated genes from two people who are carriers for the same disease come together in an embryo, the child born will develop the disease.
At our centre we carry out a genetic compatibility test on all our egg donors, checking for mutations of the most common diseases. In egg donation treatments, this test is also carried out on the recipient’s partner. This avoids the possibility of a mutation coinciding in the same reproductive couple by selecting an egg donor who is not a carrier of the same disease, minimising the risk of genetic transmission to the offspring, as indicated in Law 14/2006 on Assisted Reproduction.
