New noninvasive fetal sequencing test screens 23,000 genes without pregnancy risk

The technology addresses maternal concerns about invasive testing risks and stress, potentially improving outcomes for pregnancies with detected genetic abnormalities.

For generations, the desire to know a child before birth has carried a quiet burden — the choice between incomplete knowledge and the small but real risk of harm that comes with invasive testing. Researchers at the Broad Institute and Massachusetts General Hospital have now developed a technique called noninvasive fetal sequencing, or NIFS, that draws comprehensive genetic information from a routine blood sample, screening nearly 23,000 genes with accuracy rivaling procedures that require a needle in the womb. Presented this week at the European Society of Human Genetics conference, the method
