Genetic test breakthrough offers hope to millions of babies
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, a recent study found. 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.
