Thesis on reproductive ethics

Pär SegerdahlOn Thursday, February 28, Amal Matar defends her thesis in the field of reproductive ethics.

As genetic tests become cheaper and more reliable, the potential use of genetic tests also expands. One use could be offering preconception genetic screening to entire populations. Prospective parents could find out if they are carriers of the same recessive autosomal genetic condition, and could plan future pregnancies. Carriers of such genetic conditions can be healthy, but if both parents have the same predisposition, the risk is 25 percent that their child will have the disease.

Preconception genetic screening is not implemented in Sweden. Would it be possible to do so in the future? What would the ethical and social implications be? Is it likely that preconception genetic screening will be implemented in Sweden? These are some of the questions that Amal Matar examines in her thesis.

Amal Matar’s interviews with Swedish healthcare professionals and policymaking experts indicate that preconception genetic screening will not be implemented in Sweden. The interviewees expressed the opinion that such screening would not satisfy any medical need, would threaten important values ​​in Swedish society and in the healthcare system, and require excessive resources.

Amal Matar defends her thesis in the Uppsala University Main Building (Biskopsgatan 3), room IV, on Thursday, February 28 at 13:00. You find an earlier interview with Amal Matar here. If you want to read the thesis, you find a link below.

Swedish policymakers on genetic screening before pregnancy

Pär SegerdahlSome genetic diseases do not develop in  the child unless both parents happen to have the same gene. Parents can be healthy and unaware that they have the same non-dominant disease gene. In these cases, the risk that their child develops the disease is 25 percent.

Preconception expanded carrier screening could be offered to entire populations, to make everyone who so wishes more informed about their genetic vulnerabilities and better equipped to plan their partner choice and pregnancies. In Sweden, this is not relevant, but the issue could be considered in the future.

In a new article in the Journal of Community Genetics, Amal Matar (PhD student at CRB) reports an interview study with Swedish policymakers: experts at the Swedish National Council on Medical Ethics, at the Swedish Agency for Health Technology Assessment and Assessment of Social Services, and at the National Board of Health and Welfare. Amal Matar wanted to investigate how these influential experts perceive ethical and social aspects of preconception expanded carrier screening, as a new health technology.

It is exciting to get insight into how Swedish policymakers reason about offering genetic screening before pregnancy. They consider alternative financing, prioritization and costs for healthcare. They discuss Sweden as part of the EU. They reflect on what services the healthcare system needs to offer people, depending on what the test results reveal about them. They talk about the need for more research and public engagement, as well as about long-term societal effects.

Questions about responsibility, both parental and societal, struck me as extra interesting. If friends and relatives test themselves, it may seem irresponsible not to do so. Couples can then feel a social pressure to undergo the test, which makes their voluntariness illusory. The experts also saw problems in actively going out looking for disorders in people who are not sick. Society has a responsibility to help people when they are ill, but looking for disease risks in people without symptoms changes the whole evaluation of the risks and benefits of a health technology.

Amal Matar’s conclusion is that Swedish policymakers believe that preconception expanded carrier screening currently is not appropriate in the Swedish healthcare system. The reason commonly used in favor of screening, that it supports well-informed reproductive decision-making, was considered insufficient by the experts if the screening is financed through taxes. They also saw long-term threats to important values ​​in Swedish healthcare.

Genetic screening before pregnancy?

Pär SegerdahlGenetic diseases can arise in strange ways. So-called recessive diseases require that both parents have the gene for the disease. The parents can be healthy and unaware that they are carriers of the same non-dominant disease gene. In these cases, the risk that the child develops the disease is 25 percent.

In families with a history of some recessive disease, as well as in communities where some serious recessive disease is common, genetic screening before pregnancy is already used – to determine whether couples that are planning a child are, so to speak, genetically compatible.

As these genetic tests have become more reliable and affordable, one has begun to consider offering preconception genetic screening to whole populations. Since one doesn’t know then exactly which genes to look for, it’s not just about screening more people, but also about testing for more recessive traits. This approach has been termed expanded carrier screening (ECS).

In the Netherlands, a pilot project is underway, but the ethical questions are many. One concerns medicalization, the risk that people begin to think of themselves as being more or less genetically compatible with each other, and feel a demand to test themselves before they form a couple and plan children.

Sweden has not yet considered offering expanded carrier screening to the population and the ethical issues have not been discussed. Amal Matar, PhD student at CRB, decided to start investigating the issues in advance. So that we are prepared and can reason well, if preconception expanded carrier screening is suggested.

The first study in the PhD project was recently published in the Journal of Community Genetics. Interviews were made with clinicians and geneticists, as well as with a midwife and a genetic counselor, to examine how this type of genetic screening can be perceived from a Swedish health care perspective.

Ethical issues raised during the interviews included medicalization, effects on human reproductive freedom, parental responsibility, discrimination against diseased and carriers, prioritization of resources in health care, as well as uncertainties about what to test for and how to interpret results.

The study serves as an empirical exploration of the ethical issues. Some of these issues will be examined philosophically further on in Amal Matar’s project.
