Change the embryowet to prevent serious illnesses: “Let this be a choice of prospective parents and their doctors, not politics”

So far, desire parents can only protect their children through an IVF process with embryo selection from getting a hereditary disease. Embryos selection may not yet be applied to prevent a child from becoming the wearer of the disease; Then someone has the hereditary construction, but the disease does not (yet) express itself. The latter must change a proposal from Jan Paternotte (D66) and Harry Bevers (VVD). They want to change the embryowet.

For example, the preventing someone is to be the carrier of a disease is relevant in the Duchenne muscle disease. The disease can be passed on through a genetic error on the X chromosome, of which women have-generally-two and men one. If one of the X chromosomes in women contains the incorrect gene, the other person can still compensate for it. Boys certainly get sick with their one X chromosome. “Already in childhood their muscle function is deteriorating, from the age of ten they often need a wheelchair. In the teenage years they can no longer use their arms well and later they are dependent on artificial ventilation,” says Elizabeth Vroom of the World Duchenne organization. People with Duchenne are often not older than thirty years.

Selecting on a hereditary disease is really different from embryo selection to influence gender or eye color

Women are only technically seen as carriers of the genetic defect, while they can indeed experience complaints, for example at the heart. Now wishing parents with a high risk of passing on Duchenne’s disease can only select on healthy boys’ embryos during an IVF process. According to the current embryowet, they are not allowed to choose to eliminate a girlsembryo with an ‘unhealthy’ X chromosome. This way they cannot prevent their daughter from having to enter the same complicated process to have a healthy child themselves later. Vroom: “It would be nice if parents got that choice. That this is not decided for them.”

Desire

That is what D66 and VVD think so. Harry Bevers calls passing on carriers a “devil’s dilemma” for parents. “You have a desire to have children, but you don’t want your child to get sick and you don’t want to pass on the disease to subsequent generations.” Jan Paternotte: “We say: Let this be a choice of wish parents and their doctors, not from politics. A hereditary disease is something that families can hold for generations for generations. If science enables us to prevent serious suffering, we are obliged to make it possible.”

In 2022, Paternotte, then with VVD colleague Sophie Hermans, submitted the first proposal for the change in the law. After a few adjustments on the advice of the Council of State, it is now ready to go to the Lower House.

An IVF process with embryo selection is only carried out in the Netherlands by the Maastricht UMC, a medical-ethical committee determines which diseases this is permitted. In addition to Duchenne, these are, for example, cystic fibrosis and the blood clotting disease hemophilia. In the last thirty years, around 1,800 children have been born after embryo selection, is on the website from the hospital.

Problematic

Embryos selection to prevent carriers is particularly sensitive to the Christian parties. People who are only carriers of a hereditary disease can lead a relatively healthy life, according to the CDA. Destroying these embryos is therefore problematic, stated the party’s scientific institute in 2022 in a report.

Other medical-ethical issues also play a role in the amendment to the law. Because to what extent can you make choices for the next generation? Is there a social pressure for parents to opt for embryo selection due to the change in the law? And when will an IVF process turn into people cosmetically?

If you talk about this with involved parents, you will feel how the dilemma presses on people. Then you understand why they want to protect their children from that

According to the two MPs, that limit is not yet in sight. Paternotte: “Selecting on a hereditary disease is really different from embryo selection to influence gender or eye color, as happens in the United States. We don’t want that and we exclude it completely.”

Whether the bill can count on a majority in the Chamber is not yet forgotten. Not least because of the elections on October 29. Many parties choose to make this a free issue with moods about medical-ethical topics, so that MPs do not have to follow the line of their party at the vote. Paternotte: “It will be exciting. If necessary, we will visit 148 MPs to tell them why this is an important bill.” Bevers: “If you talk about this with involved parents, you feel how the dilemma presses on people. Then you understand why they want to protect their children from it.”
