CINCINNATI (AP) — A recent study showed that tests for sick newborns that look at their full genetic blueprints are nearly twice as good at finding genetic problems as narrower, more commonly used tests. According to the research, published in the Journal of the American Medical Association, the broader tests found 49% of genetic abnormalities, compared with 27% for the narrower tests. Experts say this offers hope to parents of millions of babies with confounding conditions. Whole genome testing found a rare bleeding disorder in Brynn Schulte of Cincinnati. Her parents say the early diagnosis and quick treatment saved her life. She’s an active 4-year-old today.
