Prenatal whole genome sequencing: Just because we can, should we?
Date:8/10/2012

the quality and quantity of information may augment parents' anxiety. "To the extent that parents now think of their child as a 'clean slate' during pregnancy, the prenatal image of a normal, healthy baby will be dramatically altered by this technology," the authors write. The anxiety over the results and changing views of what is "normal" could lead to an increase in pregnancy terminations.

Apart from reproductive decisions, the authors also foresee whole genome prenatal testing having a negative impact on child rearing. For example, if parents were able to get genetic information suggesting that their child's predicted IQ may be low, they might not strongly encourage and support the child's efforts in school.

Finally, the new technology could increase the tension between the interests of parents and children. Although parents have a strong interest in getting information that informs their reproductive choices, children have a competing interest in not knowing certain kinds of information about themselves information that could limit their autonomy as they grow into adulthood.

Given the potential harms from prenatal whole genome sequencing, the authors make four preliminary recommendations.

  • Since only some of the information will be relevant to most parents' reproductive decision-making, the medical community should make clear recommendations about which categories of information should be routinely offered to parents.

  • A child's right "not to know" his or her genetic information should not be breached unless the information is clearly useful for the parents or can improve health outcomes in the child. "We recommend that the relevant societies revise their prenatal testing guidelines to ensure that their recommendations are sufficient and appropriate for the next generation of sequencing technologies."

  • More data are needed to guide the deliberation of professional societies and the public.
