Should newborns have their genes sequenced to screen for congenital disorders?

This article or excerpt is included in the GLP’s daily curated selection of ideologically diverse news, opinion and analysis of biotechnology innovation.

For 51 years, newborn babies have gotten a heel-prick test in which their blood is screened for dozens of congenital disorders. Routine newborn screening has basically eliminated the risk of death or irreversible brain damage that some of these disorders can pose if they are not identified right away.

Now some researchers in Boston are trying to find out if genomic sequencing at birth would be as successful.

The BabySeq project is the first randomized, controlled trial to measure the harms and benefits of newborn genomic sequencing. One of four NIH-funded projects granted a total of $25 million to examine genomic sequencing in newborns, BabySeq recently enrolled its first four subjects, three healthy babies and one baby from the neonatal ICU.

The central question for this project is what will come of giving genomic information to parents and their baby’s doctor. Will doctors order more tests and interventions? Will those tests and interventions make babies healthier? Or will they just waste money, or even end up doing more harm than good?

“There is no scientific consensus that it is appropriate or useful to sequence healthy individuals,” says Robert Green, co-leader of the trial. “Therefore, the only way this would be considered a public health mandate would be if we had a tremendous amount of evidence that sequencing a large number of people would be beneficial.” 

Whatever they find, positive or negative, will be important for the future of population-wide genomic sequencing. “I think it starts asking the right questions,” says Muin Khoury, director of the CDC’s Office of Public Health Genomics. “The whole ethical ramification of this is that newborns have no choice to make, so parents have to make that decision for them.”
