Use of Prenatal Exome Sequencing: Opinion Statement of the French Federation of Human Genetics Working Group.

OBJECTIVE

Prenatal whole exome sequencing (pES) is increasingly prescribed for fetuses with ultrasound anomalies. Starting from the local French prenatal medicine practice, healthcare system and legal landscape, we aimed to address the broad medical and ethical issues raised by the use of pES for women and couples as well as for prenatal care providers.

METHOD

The French Federation of Human Genetics established a working group composed of clinicians and biologists from all over France to discuss pES challenges. A literature review was also performed.

RESULTS

We emphasize the importance of non-directive information that helps couples make a decision that is consistent with their personal values and ideas. We address the difficulty of obtaining informed consent that respects the couple's autonomy, despite the complexity of the information and regardless of their level of education and cultural background. We address whether variants of uncertain significance and unsolicited results should be reported. We emphasize the need for national harmonization of access to pES and the need for multidisciplinary meetings in complex situations. We point out that the specific French context of healthcare financing and the French law have a major influence on medical care organization and support for couples. The outcome of the working group is the development of 12 proposals.

CONCLUSION

This opinion statement, dedicated to prenatal care providers worldwide although linked to the French context, will provide food for thought and assist them in understanding the complexity and implications of pES.
